中文摘要：

Functionalized cyclopentenes could be prepared through Sm/TMSCl/t-BuOH mediated hy-drodimerization cyclization of gem-diactivated alkene in one-pot at mom temperature. The trans- or trans, transform isomer is in the majority and the major product was isolated from its stereoisomers through the fractional crystallization method.
