Starting from 6-isopropyl-7-methoxy-1-tetralone 2, a new synthesis of (+/-)
-pisiferic acid 1 has been achieved. The salient features of the present sy
nthesis are (i) facile conversion of 2 into the cis-fused octahydrophenanth
renone 5, (ii) efficient transformation of 5 into the triester 7, and (iii)
conversion of 7 into 1 involving Dieckmann cyclisation as a key reaction.
