[GRAPHICS]A stereoselective synthesis of 6-8-6 fused carbocyclic systems based on enol alkylation, ketone allylation, RCM, and Heck cyclization was developed to obtain compounds with a carbon framework that mimics the putative transition structure of the isomerization of previtamin D-3 to vitamin D-3.
