The key steps of a newly developed annulation method involve (a) reaction of cyclic S-trifluoromethanesulfonyloxy a,S-unsaturated esters (e.g. 14-16) with lithium --(phenylthio)(trlmethylstannyl)cuprate, (b) alkylation of the resultant products (e.g. 17-19) -with l,wdihaloalkanes, and (c) transmetal
