Four-Component Reaction of Alkyl Isocyanide, Acetylenic Esters, Phenols and Pyrrole; Synthesis of Dialkyl 2-[(alkylimino)(1H-pyrrol-2-yl)methyl]-3-(aryloxy) Succinate

Isocyanide-based multicomponent reactions in the synthesis of heterocycles

In this review, we update our previous presentation, underscoring the recent applications of isocyanides as privileged synthons in the synthesis of various heterocyclic compounds, especially focused on those synthesizedviamulticomponent reactions.

Three-Component Reaction of Alkyl Isocyanide, Acetylenic Diesters and 5-Hydroxy-5- Arylpyrimidine-2,4,6(1H,3H,5H)-Trione

A three-component reaction of an alkyl isocyanide, an acetylenic diester and 5-hydroxy-5-arylpyrimidine-2,4,6(1H,3H,5H)-trione provides an efficient route for the synthesis of dialkyl 2-(alkylamino)-5-(4-nitrophenyl)-7,9,11-trioxo-1-oxa-5,8,10-triazaspiro[5.5]undec-2-ene-3,4-dicarboxylate derivatives.
