Nitrene-transfer from azides to isocyanides: Unveiling its versatility as a promising building block for the synthesis of bioactive heterocycles

Autor: Devesh M. Sawant, Gaurav Joshi, Arshad J. Ansari

Publikováno v: iScience, Vol 27, Iss 4, Pp 109311- (2024)

Summary: Cross-coupling azide and isocyanide have recently gained recognition as ideal methods for efficiently synthesizing asymmetric carbodiimides. This reaction exhibits high reaction rates, efficiency, and favorable atom/step/redox economy. It en
