The first synthesis of 4,8‐dihydro‐bis‐furazano[3,4‐b:3′4′‐e]pyrazine bearing 2,2‐bis(methoxy‐NNO‐azoxy)ethyl groups has been developed. These compounds are obtained by aza‐Michael reaction of 1,1‐bis(methoxy‐NNO‐azoxy)ethene or its equivalents, such as 2,2‐bis(methoxy‐NNO‐azoxy)ethanol derivatives, with 4,8‐dihydro‐bis‐furazano[3,4‐b:3′4′‐e]pyrazine.
已开发出带有2,2-双(甲氧基-NNO-氮杂氧基)乙基的4,8-二氢-双呋喃并[3,4- b:3'4'- e ]吡嗪的第一个合成物。这些化合物是通过1,1-双(甲氧基-NNO - z氧基)乙烯或其等同物的氮杂-迈克尔反应得到的,例如2,2-双(甲氧基-NNO-)氧基)乙醇衍生物与4,8-二氢-bis-furazano [3,4- b:3′4′- e ]吡嗪。

Mesylate of 2,2-bis(methoxy-NNO-azoxy)ethanol readily reacts with sodium azide without addition of bases affording 1-azido-2,2-bis(methoxy-NNO-azoxy)ethane. In reactions of bistriflates of 2,2-bis-(methoxy- and ethoxy-NNO-azoxy)propane-1,3-diols with sodium azide in DMSO 1,3-diazido-2,2-bis-(methoxy- and ethoxy-NNO-azoxy)propanes form in a high yield. These diazides react with phenylacetylene to give 2,2-bis(methoxy-NNO-azoxy)-1,3-bis(4-phenyl-1H-1,2,3-triazol-1-yl)propane and 2,2-bis-(ethoxy-NNOazoxy)-1,3-bis(4-phenyl-1H-1,2,3-triazol-1-yl)-propane. The molecules of the obtained azides are prone to association in CDCl3 by alkoxyazoxy groups.
