Abstract
16-Epiestriol 16- and 17-monoglucuronides (XI, V) were prepared from 3-benzyloxy-17β-hydroxyestra-1, 3, 5 (10)-trien-16-one (I) employing Koenigs-Knorr reaction as shown in Chart 1. These synthetic glucuronides readily underwent hydrolysis with beef-liver β-glucuronidase preparation to furnish 16-epiestriol and free glucuronic acid.
