Article abstract of DOI:10.1016/S0040-4039(00)85931-6

An efficient, stereospecific synthesis of 25-hyroxy-7,8-dihydroergosterol, starting from the aldehyde 3 (7 steps, 30percent overall) was developed.Key steps are the stereospecific displacement of an allylic carbamate by Li2Cu3(CH3)5 and the stereoselectiv
