Studies on the synthesis of α−iodoaziridines and improved conditions for the synthesis of alkyl-α-iodoaziridines using ClMgCHI2 [PDF]
, 2015 α-Iodoaziridines are unusual motifs and intriguing structures for further functionalisation of the intact aziridine. The preparation of N-protected α-iodoaziridines is achieved through an addition-cyclisation reaction of LiCHI2 with imines.
