摘要

[GRAPHICS]
The reaction of organozinc reagents (ZnEt2, ZnPh2) with cyclic 1,3-diene monoepoxides in the presence of CF3COOH gave the cis-addition products. Lewis acids such as (CF3CO2)(2)Zn and ZnCl2 mediated the nucleophilic addition of ZnEt2 to cyclooctadiene monoepoxide with high stereoselectivity.
