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

摘要

3-Phenyl- and 3-methyl-5-(2-chloro-1-nitroalkyl)-1,2,4-oxadiazoles reacted with piperidine,pyrro-lidine,and morpholine to give the corresponding 5-(2-amino-l-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-nitro-ethyl p-tolyl sulfones.
