Acid promoted cyclisation of homochiral (R)-N-(3,4-dimethoxyphenethyl) halostachine chromium tricarbonyl is stereospecific, proceeding with retention of configuration, to afford, after decomplexation, homochiral (+)-(R)-1-phenyl-3-methyl-1,2,4,5-tetrahydrobenz[d]azepine.
酸促进的纯手性(R)-N-(3,4-二甲氧基苯乙基)卤代鸟嘌呤三羰基铬铬的环化反应具有立体特异性,保留构型,解配后可提供纯手性(+)-(R)-1-苯基-3 -甲基-1,2,4,5-四氢苯并[d]氮杂。
