Synthesis of new modified aza heterocycles on the basis of 5-(2-chloro-1-nitroalkyl)-3-phenyl-and 5-(2-chloro-1-nitroalkyl)-3-methyl-1,2,4-oxadiazoles

Abstract

3-Phenyl-and 3-methyl-5-(2-chloro-1-nitroalkyl)-1,2,4-oxadiazoles reacted with piperidine, pyrrolidine, and morpholine to give the corresponding 5-(2-amino-1-nitroalkyl) derivatives, while their reactions with sodium p-toluenesulfinate led to the formation of 2-[3-methyl(or phenyl)-1,2,4-oxadiazol-5-yl]-2-nitroethyl p-tolyl sulfones.
