Imidoyl chlorides, generated from isocyanides and acyl chlorides, react with trialkylphosphites, in a Perkow‐type reaction, to afford 3‐(alkylimino)‐2‐[(dialkyloxyphosphoryl)oxy]acrylates, which undergo a smooth reaction with tosylmethyl isocyanide (TsMIC) to furnish 4‐(alkylamino)‐3‐[(dialkyloxyphosphoryl)oxy]‐5‐[(4‐methylphenyl)sulfonyl]‐3H‐pyrrole‐3‐carboxylates in moderate‐to‐good yields.
Alkyl 2-(alkylamino)-3-(quinolin-2-yl)indolizine-1-carboxylates were prepared by1,3-dipolar cycloaddition of azomethineylides with phosphorylated hydroxyketenimines, generated in situ by a Nef isocyanide–Perkow cascade.

We present herein a new access to indolizine derivatives involving 1,3-dipolar cycloaddition of pyridinium ylides with phosphorylated hydroxyketenimines. These ketenimines are easily formed via a Nef-Perkow cascade involving isocyanides as starting material.

ABSTRACT A novelsynthesis of cyclic ketene dithioacetals through the reaction between phosphorous-based ketenimines [generated in situ from Nef-isocyanide-Perkow reaction], cyclic 1,3-dicarbonyl compounds, and carbon disulfide at room temperature, in moderate to good yields (65–80%), is described.
