| 摘 要： | INTRODUCTION Carbon-carbon bond formation is the essence of organic synthesis and the reductive dimerization of carbonyl derivatives by means of active metals is one of the most valuable methods for establishing carbon-carbon bonds. The reported reductive cyclo- dimerization of a,b-unsaturated nitriles provides novel access to functionalized five-membered ring products (Fan and Zhang, 2001; Zhong and Zhang, 2000; Zhou and Zhang, 1997; 1998). The products of enamine comprise important s…
