  摘要：

  Dimorpholinobicyclo[3.1.0]hexanecarbonitrile diastereomers la and 8a have been synthesized with high stereoselectivity starting from dichloroenamines 11 and 13. The sequence 11 --> 17 --> 19 and reductive amination of the latter provided isomer la. Ring closure of 13 by cyanide and subsequent dechlorination of 14 produced compound 8a. The stereochemistry of the cyclopropane forming reaction was studied using cis and trans isomers of chloroenamine 12: trans 12-t gave almost exclusively 3 alpha-morpholine derivatives 4a / 8a upon interaction of cyanide. Cis 12-c led to 3 alpha- and 3 beta-morpholine products 4a / 8a and 1a / 5a in a ratio of 3:1 indicating an aminoallylcation intermediate 30 in the former case. Cis-configuration of chloroenamine isomer 12-c was established by X-ray structural analysis.
