In the title compound, C24H25O7P, the δ-valerolactonyl ring exists in a distorted screw-boat conformation with the diethoxyphosphoryl substituent occupying an axial position. The latter adopts an almost syn-periplanar conformation around the P—C bond. The molecules form centrosymmetric dimers connected by O—H⋯O hydrogen bonds.

The solution 1,3-dihydroxynaphtalene in CH2Cl2, trifluoromethanesulfonic acid and (E)-2-diethoxyphosphoryl-3-(4-methoxyphenyl)acrylic acid were added and a resulting mixture was left at room temperature for 1 day. After the acrylic acid was completely reacted, saturated NaHCO3 solution was added. The organic layer was separated, washed with water and dried over MgSO4. Evaporation of the solvent under reduced preasure gave a crude product which was purified by
and recrystalized from diethyl ether.H atoms were located on difference Fourier maps and refined as riding on their carrier O or C atoms with Uiso(H) = 1.2Ueq(O or C). The methyl groups were allowed to rotate about their local threefold axis. AFIX 84, AFIX 14, AFIX 24, AFIX 44 and AFIX 138 procedures as in SHELXTL (Sheldrick, 2008) were applied.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The 4-aryl-3,4-dihydrocoumarin (neoflavonoid) moiety is found in several natural compounds which show a wide range of biological activities. Among them, the anti-inflammatory, anti-oxidative and anti-aging properties are best recognized (Zhang et al., 2006). A number of neoflavonoids isolated from various plant sources revealed cytotoxic and chemopreventive activity against cancer (Bailly et al., 2003). Morever, some 4-aryl-3,4-dihydrocoumarin derivatives exhibit estrogenic activity (Roelens et al., 2005). The most common method for the synthesis of 4-aryl-3,4-dihydrocoumarins involves Michael type addition of electron-rich hydroxyarenes to cinnamic acids or their derivatives (Aoki et al., 2005; Li et al., 2005; Rizzi et al., 2006). Unfortunately this method is limited to the reactions of cinnamic acid bearing electron-donationg groups on the aromatic ring. Recently we developed a novel synthesis of the dihydrocoumarins based on CF3SO3H promoted Friedel Crafts reaction of electron-rich hydroxyarenes (Krawczyk et al., 2007a) with the (E)-3-aryl-2-(diethoxyphosphoryl)acrylic acids. The title compound (I) is a key product of that synthesis.
The title compound (I) represents a novel dihydrocoumarine analog in which the δ-valerolactone ring bears the P—C bond. A related compound (II) in which the electron-donating para-methoxy substituent was replaced by the electron-withdrawing Br atom has been published by us recently (Krawczyk et al., 2007b). A search of the Cambridge Structural Database (Version 5.29; Allen, 2002) showed that crystal structures of the related compounds have not been reported so far.
A view of (I), with atom numbering scheme is shown in Fig. 1. The δ-valerolactone and naphtalene moieties are almost coplanar with one another. The former ring adopts conformation close to a 4S3 screw-boat (Boeyens, 1978), with O1, C1, C3, C4 and C9 almost coplanar (the average r.m.s. deviation from the mean plane is 0.09 Å) and C2 situated at the flap. The Cremer & Pople (1975) puckering parameters for the ring atom sequence O1/C1/C2/C3/C4/C9 are: Q = 0.489 (2) Å, θ = 113.6 (2)° and ϕ = 327.5 (3)°. Both exocyclic substituents, namely the diethoxyphosphoryl and phenyl groups occupy axial positions in respect to the δ-valerolactone ring.
The former group adopts an almost synperiplanar conformation along the P—C2 bond (Fig. 2). This arrangement is stabilized by electrostatic interactions of the oppositely charged phosphoryl O4 (-0.70 e) with the carbonyl C1 (0.79 e) atoms [the C1···O2 distance is 2.966 (2) Å] Atomic charges derived from electrostatic potentials were calculated using GAUSSIAN03 (Frisch et al., 2004) at the MP2/6-311++G(d,p) level for the X-ray determined coordinates. Grid points were selected according to the CHELPG procedure of Breneman & Wiberg (1990).
The phosphorus atom is located within the center of distorted tetrahedron with valency angles ranging in value from 99.90 (9) to 115.74 (11)°. On average the O—P—O type angles [111.6 (2)°] are larger then O—P—C [106.9 (2)°]. This is a general feature, often encountered in phosphorus compounds, indicating a significance of repulsive Coulombic type interactions between the oxygen atoms bearing the negative charge (Gillespie & Popelier, 2001).
A superposition of structures (I) and (II), as presented in Fig. 3, clearly shows similarity of the neoflavonoid fragments. The major difference is position of the O5—C22—C23 diethoxy group. In (I) this group points away from the naphtalene fragment while in (II) it is almost paralel and involved in the C—H—π(arom) interaction. The latter stabilizes a virtual eclipsed conformation along the axial P—C bond as was found in (II).
In the crystal molecules form centrosymmetric dimers connected by strong, practically linear hydrogen bonds linking phosphoryl and hydroxyl groups of both monomers. In terms of Etter's graph-set terminology (Etter, 1990; Bernstein, et al., 1995) this system can be described as R22(20).
