摘要

A domino olefin metathesis reaction of 1-alkyl-3-(allyloxy)-7-oxabicyclo[2.2.1]hept-5-enes 7 produced the fused bis(oxacyclic) structure for dysiherbaine and neodysiherbaine A (i.e., 6b) with the complete control of the relative stereochemistry at the quaternary carbon center and the ring junction of the dysiherbaine core skeleton. A formal total synthesis of dysiherbaine and neodysiherbaine A was achieved from 6b.
