摘要
A protocol has been devised for the synthesis of 3-substituted 5-amino-1,2,4-thiadiazoles utilizing isothiocyanates, amidoximes and water as an eco-friendly solvent. The strategy involves consecutive C-N and S-N bonds formation in a one-pot reaction under catalyst-free conditions. Operational simplicity, low cost, broad substrate scope and readily available starting materials are the main features of this protocol.
