N,N-dimethylchlorosulfitemethaniminium chloride formed from thionyl chloride and dimethylformamide was found and efficient reagent for the synthesis of acyl azides from carboxylic acids and nitriles from oximes. It is also highly efficient for the direct synthesis of beta-lactams from carboxylic acids and imines avoiding the use of acid chlorides.
发现了由亚硫酰氯和二甲基甲酰胺形成的N,N-二甲基氯亚硫酸氯甲铵,是由羧酸和肟合成酰基叠氮化物的有效试剂。从羧酸和亚胺直接合成β-内酰胺也非常高效,避免了使用酰氯。
