Benzylic, allylic, propargylic and unactivated alcohols can be oxidised with activated manganese dioxide in the presence of N-methoxy-N-methyl-2-(triphenylphosphoranylidine)acetamide to generate directly the corresponding α,β-unsaturated Weinreb amides. Elaboration of the resulting Weinreb amides is also described, in particular as part of a new route to analogues of the arachidonic acid metabolite
可以在N-甲氧基-N-甲基-2-(三苯基膦基甲酰基)乙酰胺的存在下,用活化的二氧化锰将苯甲酸,烯丙基,炔丙基和未活化的醇氧化,以直接生成相应的α,β-不饱和Weinreb酰胺。还描述了所得Weinreb酰胺的制备,特别是作为花生四烯酸代谢物5-氧代-6 E,8 Z,11 Z,14 Z-二十碳四烯酸类似物的新途径的一部分。
