A stereocontrolled synthesis of the Prelog-Djerassilactone (28) is described; all the stereocontrol stems from the high diastereoselectivity of electrophilic attack on a double bond adjacent to a chiral centre carrying a silyl group.

β-silyl ester, the enolate alkylation 11→12 of a β-silyl ester, silyl-to-hydroxy conversion with retention of configuration 13→14, and stereospecifically anti protodesilylation of the allylsilanes 26 and 27 giving largely the alkene 28. These allylsilanes had themselves been prepared in a stereocontrolled, convergent synthesis from the allylic acetates 24 and 25, providing thereby a general solution to the
