25R)-3/3,26-Dihydroxy-5c~-cholest-8( 14)-en-15-one (1) was synthesized in four steps from (25R)-3/3,26-diacetoxycholesta-5,7-diene (111) in 30% overall yield, lsomerization of 111 with HCI in chloroform-dichloromethane at -60°C gave (25R)-3/3,26-diacetoxy-5et-cholesta-7,14-diene together with the 5u
Hydroboration of 5a-cholesta-8,14-dien-3fl-ol ( ) gav e 5a-cholest-8-en-3CLl5a-diol (IV) in 89% yield. 5a-Cholest-7-en-3/3,15a-diol (V) was prepared in 91% yield by hydroboration of 5ct-cholesta-7,14-dien-3/3-ol (H). Hydroboration of 27:63 mixture of I and H gave IV and V in 18% and 70% yields, resp
