The reduction of substituted isoflavones with sodium borohydride catalyzed by cobalt(ii) phthalocyanines has been achieved efficiently to yield cis- and trans-isoflavan-4-ols under mild conditions via the formation of a hydridocobalt(iii) phthalocyanine i

The solution-state conformational equilibria of trans-4′ ,7-dihydroxyisoflavan-4-ol (1) and transisoflavan-4-ol (2) were assessed based on the temperature dependence of their vicinal coupling constants J H-2α,H-3 and JH-3,H-4 in comp
Facile reduction of aromatic aldehydes, ketones, diketones and oxo aldehydes to alcohols by an aqueous TiCl3/NH3 system: Selectivity and scope

A simple and rapid procedure for the almost quantitative reduction of aromatic aldehydes, ketones, diketones and oxo aldehydes to alcohols by use of TiCl3/NH3 in aqueous methanol solution is reported. The reducing system distinguishes between different classes of aldehydes and/or ketones, and many functionalities that usually do not survive under reducing conditions are tolerated well. The concept of reversal of chemoselectivity has also been developed. A mechanism based on two sequential one-electron transfers from TiIII to the carbonyl carbon atom is proposed, the second SET becoming operative only in the presence of ammonium ion (either added or formed in situ).
