P(III)‐Mediated Cascade C‐N/C‐S Bond Formation: A Protocol towards the Synthesis of N,S‐Heterocycles and Spiro Compounds

A P(III)‐mediated entry towards construction of C−N/C−S bond has been devised. The developed heterocyclization method was exercised for the synthesis of a diverse range of N,S‐heterocycles and related spiro molecules. P(NMe2)3 revealed the maximum efficacies under the aerobic reaction conditions and a spectrum of bis‐nucleophiles, and isothiocyanates were tolerated well to serve the access of manifold immense molecules.
