Diphenylboron chelate of a pyridoxal hemiacetal with ethanol

P. G. Jones, W. Kliegel and M. Barakat

Abstract: The title compound, 4-ethoxy-5-(hydroxymethyl)-8-methyl-2,2-diphenyl-1,3-dioxa-7-azonia-2-borata-1,2,3,4-tetrahydronaphthalene monohydrate, C₂₂H₂₄BNO₄·H₂O, contains a six-membered BOCCCO heterocycle with a half-chair conformation, fused to a pyridine ring. An N-HO hydrogen bond is formed between the protonated pyridine ring and the associated water molecule, and two O-HO hydrogen bonds are formed using the water H atoms. The hydroxyl H atom is involved in an O-H interaction. The residues are thus linked to form ribbons parallel to the a axis.
