Abstract

Abstract Nitration of the acetamido-nitrobenzodioxocins 10, prepared from the corresponding amino derivatives 9, led to the acetamido-dinitrobenzodioxocins 11, hydrolysis of which furnished the corresponding amines 13. Preparation of the dinitroazides 18 and acetamido-nitroazides 21 as precursors to substituted dioxocino-annelated benzofuroxans is described. Thermolysis of the dinitro-azido derivatives 18a, c, e and/or ...
