摘要

The [1+ 41 cycloadditions of isocyanides with various aryl nitroalkenes have been investigated. When the aryl groups were XCsH4, naphthyl, and 2-pyridinyl, the reactions gave the 1-hydroxyindoles, 1-hydroxybenzoindoles, and 1-hydroxy-7-azaindole. When the aryl group was thienyl or furyl, fused 1-hydroxypyrroles were obtained. The reaction of isocyanide with methyl 2-nitro-2, 4-pentadienoates gave 1-hydroxypyrroles. A mechanism ...
