The glucosylation of some coumarin and flavone derivatives on incubation with the hairy roots of morning glory (Pharbitis nil) was previously reported. We further studied the biotransformation of benzaldehyde- and acetophenone-type derivatives. Vanillin a

Phase-transfer-catalysed D-glucosylation of chelated phenolic aglucons and substituted cinnamic acids, using 2,3,4,6-tetra-O-benzoyl-α-D-glucopyranosyl bromide, resulted in the stereospecific formation of benzoylated aryl β-D-glucopyranosides and substituted-β-D-glucopyranosyl cinnamates, respectively, in good yields.The results conclusively disproved an earlier report that the phase-transfer method requires a nonparticipating group at C-2 or C-6 in the carbohydrate moiety. 1,2,3,4,6-Penta-O-benzoyl-β-D-glucopyranose was obtained as a minor side-product in all of these reactions.The possible mechanism of the phase-transfer method is discussed.
