3H-Azirino[1,2-d][1,4]benzodiazepin-4(5H)-ones: Synthesis and Stereochemistry
摘要:
The synthesis of 5-alkyl-1,9b-dihydro-3H-azirino[1,2-d][1,4]benzodiazepin-4(5H)-ones by cycloaddition of dichlorocarbene to N1-alkyl-1,4-benzodiazepine derivatives, is described. The lack of reactivity in analogous Nl-H derivatives is explained on the basis of elctronic factors.
