The pyridine ring in the title compound, C₃₉H₄₇NO₇·0.5C₂H₅OH·0.5 H₂O, is connected to one 3,3,6,6-tetramethyl-1,8-dioxoxanthenyl and one 4a-hydroxy-3,3,6,6-tetramethyl-1,8-dioxodecahydroxanthenyl substituent in the 2- and 6-positions of the ring. In the former substituent, the six-membered xanthenyl ring adopts a flattened envelope conformation (with the methine C atom as the flap) while in the latter, the six-membered xanthenyl ring adopts a twisted envelope conformation (with the C atom bearing the hydroxy group representing the flap). The hydroxy H atom forms an intramolecular hydrogen bond to the pyridyl N atom. An ethanol solvent molecule is disordered with respect to a water molecule in a 1:1 ratio. The water molecule itself is disordered over two positions of equal occupancy.

Comment top

Benzaldehyde (and its derivatives) and dimedone readily condense to form 3,3,6,6-tetramethyl-9-phenyl-3,4,5,6-tetrahydro-9H-xanthene-1,8(2H,7H)-dione (Rao et al., 2009; Reddy et al., 2009), which belongs to the pharmaceutically useful class of xanthenes. An aromatic reactant having two aldehyde groups should therefore furnish a bis-xanthene. In this study, pyridine-2,6-dicarboxaldehyde yielded the expected compound, but one water molecule has added across one of the four carbon-carbon double bonds to yield the title compound (Scheme I, Fig. 1), which was isolated from ethanol as the hemihydrated hemisolvate. The pyridine ring in the title compound, C₃₉H₄₇NO₇ × 0.5 C₂H₅OH × 0.5 H₂O, is connected to one tetramethyloctahydroxanthen-1,8-dionyl and one hydroxy-tetramethyldecahydro-xanthen-1,8-dionyl substituent in the 2- and 6-positions of the ring. The hydroxy H atom of the second substituent forms an intramolecular hydrogen bond to the pyridyl N atom.

Experimental top

Amino-iso-propanol (20 mmol), pyridine-2,6-dicarboxaldeyde (10 mol) and dimedone (40 mmol) were heated in ethanol (100 ml) for 5 h. The solution was cooled and the brown solid collected and recrystallized from ethanol to give colorless crystals, m.p. 348 K. The synthesis did not yield the expected decahydroacridine derivative (in which the iso-propylamino group would replaced the ether oxygen of the xanthene unit).
