Efficient and mild synthesis of substituted 2-amino-1,3,4-oxadiazoles mediated by (tosylimino)phenyl-γ3-iodane
A simple and convenient one-pot protocol for the synthesis of substituted 2-amino-1,3,4-oxadiazoles mediated by (tosylimino)phenyl-γ3- iodane has been described. Acylthiosemicarbazides prepared from the corresponding acylhydrazides undergo effi

Hypervalent iodine(V) mediated mild and convenient synthesis of substituted 2-amino-1,3,4-oxadiazoles
A simple protocol for the synthesis of 2-amino-1,3,4-oxadiazoles starting from the corresponding acylhydrazides by cyclodesulfurization of intermediate acylthiosemicarbazides mediated by o-iodoxybenzoic acid in good yields has been described. The protocol

Superior reactivity of thiosemicarbazides in the synthesis of 2-amino-1,3,4-oxadiazoles
(Chemical Equation Presented) A facile and general protocol for the preparation of 2-amino-1,3,4-oxadiazoles is reported. This method relies on a tosyl chloride/pyridine-mediated cyclization of a thiosemicarbazide, which is readily prepared by acylation o
