Abstract

Biaryl Sulfonamides from O-Acetyl Amidoximes: 1,2,4-Oxadiazole Cyclization under Acidic Conditions. -The reaction conditions are optimized to avoid by-products. A cyclodehydration of O-acylated amidoximes like (III) under acidic conditions is described for the first time. -(DOSA, S.; DANIELS, J.; GUETSCHOW*, M.; J. Heterocycl.
