Abstract
Five new steroidal oxalate derivatives, oxalic acid (pregn-5-en-20-one)-3β-yl ethyl ester (2), oxalic acid mono (pregn-5-en-20-one)-3β-yl ester (3), chloro-oxo-acetic acid (5β-cholan-24-oic acid methyl ester)-3α-yl ester (5), oxalic acid mono (5β-cholan-24-oic acid methyl ester)-3α-yl ester (6) and oxalic acid (5β-cholan-24-oic acid methyl ester)-3α-yl ethyl ester (7) were synthesized, respectively, from pregnenolone (1) and methyl lithocholate (4) using excess oxalyl chloride.
