Article abstract of DOI:10.1016/S0040-4020(01)86858-7

Typhasterol 2 was synthesized stereoselectively from hyodeoxycholic acid 3.The aldehyde 5 derived from 3 was reacted with the anion of 3-methylbutenolide under kinetic condition to afford (22R,23R)-7 as the major product.Hydrogenation of 7 and its 22-acet
