摘要

Organoaluminium compounds, R 3 Al, promote the Claisen rearrangement of allyl vinyl ether derivatives at room temperature under transfer of R or H as a nucleophile to the aldehydic carbon. Treatment of 1-butyl-2-propenyl vinyl ether with a hexane solution of Me 3 Al (1.0 M, 2.2 equiv) in CH 2 ClCH 2 Cl at 25° C afforded 5-decen-2-ol (91% yield, E⁄ Z= 47⁄ 53), which was produced by the [3, 3] sigmatropic rearrangement and successive ...
