Abstract
Synthesis of cyclolithocholates by using dicyclohexylcarboimide (DCC) and 4-dimethylaminopyridine (DMAP) is described. Cyclotrimerization is the principal reaction route for lithocholic acid system. These react ion conditions were less successful in the cyclization of 12-oxolithoc holic acid.
