A one-pot synthesis of novel cyclic ketene dithioacetals from Nef-isocyanide-Perkow adduct

摘要

A novel synthesis 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.
