The stereochemistry of reduction of the 1- and 16-carbonyl group in the normal and 8,13-isogibberellins
Abstract
N.m.r. and X-ray studies show that reduction of the 16-carbonyl group in the normal and 8,13-isogibberellin series by sodium borohydride affords the 16-endo-alcohols; a 1-carbonyl group affords the 1α-alcohol.
