Abstract

Enantiospecific construction of the bicyclo[4.3.0]nonan-8-one 17 employing a lithium and liquid ammonia mediated carbanion cyclisation of the $\delta$-methyl-$\delta$,$\varepsilon$-unsaturated ester 13, and its elaboration to the tricyclic framework of the marine sesquiterpenes spirodysins are described.
