N-Heterocyclic Carbene (NHC)-Catalyzed Direct Amidation of Aldehydes with Nitroso Compounds
摘要:
NHC-catalyzed direct amidation of aldehydes with nitroso compounds is a powerful method for the synthesis of N-arylhydroxamic acids. A variety of aryl, alkyl, alkenyl, and heterocyclic aldehydes were found to give excellent yields of the corresponding N-arylhydroxamic acids. This chemistry was also extended to the synthesis of chiral N-arylhydroxamic acids by kinetic resolution of a-branched aldehydes, a domino amidation-redox amination reaction of acrolein, and a three-component reaction for the synthesis of N-arylaziridines.
The invention relates to a process for making an aziridine, wherein an aldehyde, a nitroso compound and a Michael acceptor are reacted in the presence of an N-heterocyclic carbene (NHC) catalyst.

A visible-light induced decarboxylative aza-Darzens reaction between N-aryl glycines and diazo compounds was developed, which affords various mono-substituted aziridines in good yields.
The invention relates to a process for making an aziridine. wherein an aldehyde, a nitroso compound and a Michael acceptor are reacted in the presence of an N-heterocyclic carbene (NHC) catalyst.
