摘要

Synthesis of cyclolithocholates by using dicyclohexylcarboimide (DCC) and 4-dimethylaminopyridine (DMAP) is described. Cyclo- trimerization is the principal reaction route for lithocholic acid sys- tem. These reaction conditions were less successful in the cycliza- tion of 12-oxolithocholic acid.
