Hydroxymethylation Studies of o-Hydroxyphenyl Benzyl Ketones with and without the use of Phase Transfer Catalyst: A Novel Synthesis of Isoflavanones

o-Hydroxyphenyl benzyl ketones, having a resorcinol unit in ring-A, on treatment with formalin in chloroform-aq. potassium carbonate biphase system give the corresponding α-hydroxymethyl derivatives.This reaction when carried out in the presence of a phas

SYNTHESIS OF METHOXYISOFLAVONONES FROM ARYLMETHYL o-HYDROXYARYL AND PARAFORMALDEHYDE

Paraformaldehyde reacts with benzyl o-hydroxyphenyl ketones in the presence of diethylamine in methanolic solution to afford isoflavanones in excellent yields.

HYDROBORATIONS: NEW SYNTHESIS OF PSEUDO-BAPTIGENIN, O-METHYL PSEUDO-BAPTIGENIN AND CABREUVIN.

Application of hydroboration followed by chromic acid oxydation to 4-hydroxy 7-methoxy(3',4'-methylenedioxyphenyl) coumarin and 4-hydroxy 7-benzyloxy 3-(3',4'-methylenedioxyphenyl) coumarin forms the corresponding isoflavanones which are dehydrogenated into isoflavones.
