- Abstract
Propargylic pivaloates bearing an alkynyl group at a three‐carbon tether under the gold catalysis would undergo [3,3] rearrangements of propargylic pivaloates followed by tandem [2+2] cyclization to give the corresponding 6‐acylbicyclo[3,2,0]hept‐6‐ens. In continuing work, we prepared various substrates bearing two arms of alkyne‐propargylic pivaloates to explore primitive dendrimer concept bicyclic compounds. Finally, we could obtain a series of diasteromeric compounds bearing two arms of 6‐acylbicyclo[3,2,0]hept‐6‐ene groups in high yields.
