Process for preparing 3alpha(beta)-7alpha(beta)-dihydroxy-6alpha(beta)-alkyl-5beta-cholanic acid

摘要

Process for preparing 3α-7α(β)-dihydroxy-6α(β)-alkyl-5β-cholanic acid (I) in which R is a linear or branched C-C alkyl and the relative intermediates 3α-hydroxy-6β- alkyl-7-keto-5β-cholanic (VIII) and 3α-hydroxy-6α-alkyl-7-keto-5β-cholanic (IX).
