Abstract
Abstract The synthesis and 14-labeling of 3α, 7α, 12α-trihydroxy-27-carboxymethyl-5-β- cholestan-26-oic acid by two different approaches is described. One of them involves chain elongation of cholic acid via Wittig-Horner condensation of its formylated 24-aldehyde with tetraethyl phosphonoglutarate. The resulting cholestenoate, on deprotection and hydrogenation, affords the unusual C 29 bile acid in good yield. An alternative procedure ...
