| dc.description.abstract | Reaction of 5-adrosten-3β, 17β-diol diacetate with m-chloroperbenzoic acid at different temperatures and pH in a biphasic system with NaHCO3 as a phase transfer catalyst yields corresponding 5α, 6α- and 5β, 6β-epoxides, which could be separated by column chromatography. Exclusive formation of 5a, 6a-epoxide could be obtained at a low temperature (-20°C). Epoxides on treatment with different amines lead to stereospecific opening, the amino substituent entering from the opposite side at C-6. | en_US |
