摘要
The [3+2+2] cycloaddition reaction of ethyl cyclopropylideneacetate (1) and diynes proceeded in the presence of Ni(0) catalysts, and bicyclic compounds were isolated in good yields. The reaction provided a new approach to 7,6- and 7,5-fused bicyclic compounds. (c) 2007 Elsevier Ltd. All rights reserved.
