A new and general route to N-unsubstituted azomethine ylides from N-(silylmethyl)thioureas: Cycloaddition of synthetic equivalents of nonstabilized aminonitrile ylides

Article abstract of DOI:10.1246/cl.1997.945

The S-methylation of N-(silylmethyl)thioureas followed by the desilylation generates N-unsubstituted azomethine ylides having both methylthio and amino groups at the ylide carbon. These azomethine ylides react with electron-deficient olefins to give forma
