摘要

Abstract Double carbonylation of 1, 3-cyclohexadienes 1 is applied to the synthesis of substituted bicyclo [3.2. 1] oct-3-ene-2, 8-diones 4. The Lewis acid mediated ring enlargement of substituted cyclohexadiene complexes 2 produces the cycloheptanone alkyl allyl complexes 3 with high regioselectivity. Substituted bicyclic diketones 4 are obtained in high yields by treating the complexes 3 with carbon monoxide under pressure or by ...
