The stereochemistry of some reactions at C-16 in gibberellins; an X-ray crystallographic study of the methyl esters of gibberellin A2 and gibberellin A9 hydrochloride
Abstract
Hydration of the 16-ene in the gibberellins is shown, by a combination of spectroscopic and X-ray crystallographic means, to lead to (16R)-alcohols. The hydrochloride of gibberellin A9 methyl ester possesses the same (16R)-stereochemistry.
