cyclisation procedure of the carbonyl chloride Reissert adduct 14 of phthalazine. This synthetic method could be extended to the preparation of dihydro derivatives 7a to 7f and represents a new access to annelated sydnonimines. The para anisoyl and ethoxycarbonyl derivatives of these sydnonimines were also prepared with analogy to molsidomine 1 or pirsidomine 2.
通过邻苯二甲酰氯的羰基氯Reissert加合物14的原始的一锅式亚硝化和环化程序来制备亚磺胺5。这种合成方法可以扩展到二氢衍生物7a至7f的制备,并且代表了一种新的退火的亚砜亚胺的途径。这些sydnonimines的对异戊基和乙氧基羰基衍生物的制备也类似于molsidomine 1或pirsidomine 2。
