Abstract
Allene-tethered dienes (1) undergo an intramolecular and highly enantioselective (4+3) cycloaddition when treated with suitable chiral phosphoramidite/gold(I) catalysts (see scheme; Ar=9-anthracenyl). The reactions provide synthetically relevant [5.3.0] and [5.4.0] fused bicyclic systems 2 with good yields, complete diastereocontrol, and excellent enantioselectivities.
