Stereoselective reductive debromination-cyclopropanation of 2-bromo-1-phenylethylidene-malononitrile and 2-bromo-1-beta-naphthylethylidenemalononitrile by coenzyme NADH model BNAH through chiral induction in cyclodextrins is reported. The matching between substrates and cyclodextrins, the substituent effect, and the effect of cyclodextrin concentration on the optical yields have been investigated.
据报道,辅酶NADH模型BNAH通过手性诱导在环糊精中对2-溴-1-苯基亚乙基-丙二腈和2-溴-1-β-萘乙基-丙二腈进行立体选择性还原脱溴-环丙烷化。研究了底物与环糊精之间的匹配,取代基效应以及环糊精浓度对光学产率的影响。
