N-benzylcinchonidinium bromide, C26H29N2O+·Br−, with the (R)-[(2S,4S,5R)-1-benzyl-5-ethenyl-1-azoniabicyclo[2.2.2]octan-2-yl](quinolin-4-yl)methanol bromide, is a quaternary ammonium salt of the cinchona alkaloid cinchonidine. This salt is widely used as a chiral phase-transfer catalyst and chiral resolution agent. Both classical and non-classical hydrogen-bonding interactions, as well as anion effects have been shown to play key mechanistic roles in the catalysis of cinchona In an effort to understand the effects of water on these intermolecular interactions, the structures of anhydrous N-benzylcinchonidinium bromide, (I), and the sesquihydrate, C26H29N2O+·Br−·1.5H2O, (II), were determined.
1. Chemical context
Cinchona-derived enantioselective phase-transfer catalysts have been used in a variety of applications including [2,3]-Wittig rearrangements (Denmark & Cullen, 2015), synthesis of unnatural α-amino acids (O'Donnell et al., 1989), and even industrial-scale synthesis of pharmaceuticals (Moccia et al., 2015). As this class of phase-transfer catalysts are easy to prepare from the parent natural product and demonstrate aspects of green and sustainable chemistry, they are attractive organocatalysts for further development. Mechanistic studies of N-benzylcinchonidinium bromide and substrates in solution provide evidence for the importance of quaternary ammonium benzylic C—H hydrogen-bond donor interactions as well as the classical OH donor (Bencivenni et al., 2021). Anion effects also demonstrate differences in the binding mode of substrates with mechanistic implications and potential enantioselectivity.
While structures are reported for analogs of this cation, that of the commercially available bromide salt is unpublished. We report here the structures of N-benzylcinchonidinium bromide (I) and the sesquihydrate (II).
2. Structural commentary
The anhydrous compound (I) (Fig. 1) crystallizes in the monoclinic P21. The of (I) consists of one molecular cation and one bromide anion. The sesquihydrate (II) (Fig. 2) crystallizes in the tetragonal P41212. The of (II) consists of one molecular cation, one bromide anion, and one water on a general position and one half water, as O3 lies on a twofold axis at z = 0.5. For (I) and (II), the of chiral atoms N1, C2, C3, C7, and C8 are determined as S, R, S, S, and R, respectively, by and are consistent with previous structures of cinchonidine.
Most analogous bond lengths in (I) and (II) show only minor differences, with two exceptions (Tables 1 and 2). The largest differences in bond lengths occur for C6—C7 [1.510 (4) Å (I), 1.553 (8) Å (II)] and N2—C11 [1.282 (6) Å (I), 1.319 (9) Å (II)]. The quinuclidine intramolecular N1⋯C3 distances show small expansion of this bicyclic ring system from (I) [2.534 (5) Å] to (II) [2.591 (8) Å]. Overlap of the N-benzylcinchonidinium cation atom coordinates of (I) and (II) (Fig. 3) shows significant conformational differences. While the quinuclidine, benzyl, and vinyl functionalities adopt very similar conformations for (I) and (II), larger changes are observed in the alcohol and quinoline groups. Torsion angles that highlight the largest conformational changes include C7—C8—C13—C12 [107.9 (3)° (I); 101.3 (7)° (II)], C8—C7—N1—C20 [−39.0 (3)° (I); −53.6 (7)° (II)], and O1—C8—C13—C12 [−11.7 (4)° (I); −19.2 (8)° (II)]. These torsion-angle differences result in large changes in the relative angles between least-squares planes of the phenyl and quinoline groups in (I) [14.8 (2)°] and (II) [41.8 (3)°]. Intramolecular C—H⋯O contacts C5—H5A⋯O1 are found in both (I) and (II), but (I) shows an additional benzylic C20—H20B⋯O1 contact (Tables 3 and 4, Figs. 4 and 5).

3. Supramolecular features
The extended structure of (I) displays a simple isolated charge-assisted hydrogen bond with the alcohol donor O1 and Br1 anion acceptor (Table 3, Fig. 4). The quinoline N2 acceptor does not participate in any hydrogen-bonding interactions. Each bromide also has four short C—H⋯Br contacts with the same cation (phenyl, benzyl, quinoline, and vinyl) as well as an additional quinuclidine methine C—H.
The sesquihydrate (II) shows very different hydrogen-bonding interactions (Table 4, Fig. 5). The alcohol group O1 acts as a donor with a water acceptor, O2. Water O2 hydrogen bonds as donor with Br1 and quinoline N2, while water O3 acts a donor to two bromide acceptors. This pattern of hydrogen bonds forms a chain with terminal O1 donors and water and bromide links, with the water O2 relating the two halves of the chain. Quinoline N2 acceptors of O2 hydrogen-bond donors link the chains forming an extended network. Each bromide also has four short C—H⋯Br contacts with the same cation (benzyl, vinyl, and two quinuclidine) as well as two additional quinuclidine contacts with a neighboring molecular cation (Figs. 5 and 6).
4. Database survey
A search of the Cambridge Structural Database (ConQuest version 2022.1.0; Groom et al., 2016) yields several related analogs of both N-benzylcinchonidinium salts as well as the pseudo-enantiomer N-benzylcinchoninium. The 2-fluorobenzyl bromide sesquihydrate analog XUNQIG (Jew et al., 2002) is isostructural with (II) though additional C—H⋯F intra- and intermolecular interactions are present. Introduction of the aromatic 2-fluoro substituent yielded enhanced enantioselectivity in catalytic phase-transfer alkylation reactions, with possible origins related to more conformational or dipole changes to enhance substrate binding. Other closely related N-benzylcinchonidinium chloride salts have been employed in resolution of a chiral spirocyclic diol (GAJBOJ01; Zhang et al., 2006), atropisomeric chiral diols (HADSIS; Walsh et al., 2021 and JAPGIR; Sweetman et al., 2005) and a related mixed chiral amine/alcohol (GOSWIU; Ding et al., 1999). Even in the presence of multiple additional hydrogen-bond donors in these co-crystals, short benzylic C—H⋯Cl contacts are retained in GAJBOJ01 and JAPGIR, though not in HADSIS or GOSWIU. The N-benzylcinchonidinium cation has also been employed in resolution of chiral halogenated phosphates (GARJUF, GAWSUT; Frantz et al., 2005). Short benzylic C—H⋯O contacts are found in these chiral phosphate salts.
Closely related cinchoninium anhydrous bromide structures with phenyl substituents [2-bromobenzyl, QEDZAC (Skórska-Stania et al. 2012) and 3,5-bistrifluoromethyl, UHINUV (Kawai et al., 2009)] show similar O—H⋯Br hydrogen bonding to (I). However, the C—H⋯Br interactions differ. In QEDZAC, each bromide has quinuclidine, quinoline, and benzyl C—H⋯Br contacts with the same cation. In UHINUV, quinoline, benzyl, and phenyl C—H⋯Br contacts with the same cation are found. The N-benzylcinchoninium chloride salt has also been employed in a resolution of BINOL (WOMQUK01; Walsh et al., 2021).
5. Synthesis and crystallization
N-benzylcinchonidinium bromide was purchased from Sigma-Aldrich (St. Louis, Missouri, USA). Crystals of the anhydrous form (I) were obtained by vapor diffusion of diethyl ether into an acetonitrile solution of N-benzylcinchonidinium bromide. Crystals of the sesquihydrate (II) were obtained by slow evaporation of an ethanol solution of N-benzylcinchonidinium bromide.
6. Refinement
Crystal data, data collection and structure . The O—H hydrogen positions were assigned from residual electron-density peaks and positions were refined. All remaining hydrogen atoms were placed in calculated positions and refined in the riding-model approximation with distances of C—H = 0.93, 0.93, 0.93, 0.97, and 0.98 Å for the aromatic C—H, terminal vinyl CH2, vinyl C9—H9, methylene C—H, and methine C—H, respectively, and with Uiso(H) = k·Ueq(C), k = 1.2 for all C—H and 1.5 for the hydroxyl H1.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
