| Abstract: | This report describes the synthesis of 3α, 6β, 11β, 17α, 21-pentahydroxy-5β-pregnane-20-one, 3α, 6β, 11β, 17α, 21-pentahydroxy-5α-pregnane-20-one, 3α, 6α, 11β, 17α, 21-pentahydroxy-5β-pregnane-20-one, 3α, 6α, 11β, 17α, 21-pentahydroxy-5α-pregnane-20-one, 3α, 6β, 17α, 21-tetrahydroxy-5β-pregnane-11, 20-dione, 3α, 6β, 17α, 21-tetrahydroxy-5α-pregnane-11, 20-dione, 3α, 6α, 17α, 21-tetrahydroxy-5β-pregnane-1 1, 20-dione and 3α, 6α, 17α, 21-tetrahydroxy-5α-pregnane-11, 20-dione.The gas chromatographic-mass spectrometric properties of these compounds are given. Proof of structure was accomplished using gas chromatography-mass spectrometry, microchemical reactions, optical rotatory dispersion and nuclear magnetic resonance spectroscopy. |
