Aziridination of alkenes with N-substituted hydrazines mediated by iodobenzene diacetate
摘要:
Aziridination of a variety of alkenes with N-substituted hydrazines mediated by iodobenzene diacetate under mild conditions (K2CO3, CH2Cl2) and ambient temperature were achieved in good to excellent yields (up to 99%), and conversions. The practicality and simplicity of this C-N bond formation protocol was exemplified by its application to the aziridination of cholesteryl acetate in a stereoselective manner. (C) 2004 Elsevier Ltd.

Aryl iodide mediated aziridination of a variety of alkenes with N-aminophthalimide under mild conditions (m-CPBA, K(2)CO(3), CH(2)Cl(2), 25 degrees C) was achieved in moderate to good yields (up to 94%). By recovering the aryl iodide, a recyclable system is developed with product yield over 79% attained for the aziridination of trans-1,2-diphenylethylene.
