REGIOCONTROLLED SYNTHESIS OF THE ERGOSTEROL B-ISOMERS
Dolle, Roland E.,Schmidt, Stanley J.,Kruse, Lawrence I.
, p. 1581 - 1582 (1988)
A novel, regiocontrolled synthesis of the ergosterol B-isomers, (1), (2) and (3) is described, the success of which was realized via the highly regioselective formation of intermediate trienoltriflates, (7), (8) and (9).
