An unprecedented intermolecular nucleophilic attack of C═X bonds (X = O and S) on the rhodium(I)-carbenes has been developed. This transformation allows for the coupling–cyclization of aroylamides with α-diazoketones and provides concise access to 2,4,5-trisubstituted 1,3-oxazoles and 1,3-thiazoles with a broad tolerance of functional groups.
已经开发了前所未有的C ofX键(X = O和S)对铑(I)-卡宾的分子间亲核攻击。这种转变可以使芳酰胺与α-二氮杂酮偶合-环化,并提供对官能团具有广泛耐受性的2,4,5-三取代的1,3-恶唑和1,3-噻唑的简捷途径。
