Triazolines. 25. 1,3-Cycloaddition of aryl azides to enamides and the synthesis of 1-aryl-5-amido-1,2,3-triazolines
摘要:
This paper describes for the first tune the 1,3-dipolar cycloaddition of aryl azides to the vinylic bond of enamides, represented by the N-vinyllactam N-vinyl-2-pyrrolidinone (NVP) (Ia) and the open-chain enamide, N-methyl-N-vinylacetamide (NVA) (Ib). Mecharustically, enamides react like enamines in azide cycloaddition reactions to yield 1-aryl-5-amido-1,2,3-triazolines (II).
