structurally unique and hitherto unexplored 2,3-dihydrodiazete N-oxides in moderate to high yields. The products possess a highly strained four-membered ring structure containing two nitrogen atoms. The synthetic applicability of the products was also demonstrated by many important conversions to diverse nitrogen-containing compounds.
开发了由 α-溴肟和N-甲苯磺酰氧基氨基甲酸酯原位生成的 α-亚硝基苯乙烯的前所未有的 (3+1) 环化,这使得能够合成一系列结构独特且迄今为止尚未开发的 2,3-二氢二氮杂氮氧化物中到高产。该产品具有高度应变的四元环结构,包含两个氮原子。产品的合成适用性也通过许多重要的转化为不同的含氮化合物来证明。
