The first cnantioselective total synthesis of (-)-13-hydroxy-11,12- pl,epox
y-neocembrene (1), a naturally occurring cembranoid isolated from sort cora
l Sarcophyton trocheliophorum. was achieved via a general approach by emplo
ying intramolecular McMurry coupling as a key step from (S)-(+)-carvone. Th
e absolute configuration of the epoxide function of 1 is concluded as (11S,
12S).
