  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。

  Direct syntheses of 4,5-dihydro-pyrazole, pyrazolidine, and 1,2-dihydro-phthalazine derivatives via double-alkylation of hydrazines by alkyl dihalides or ditosylates were accomplished in aqueous media under microwave irradiation conditions; the environmentally friendlier chemical transformation occurred in a single step and eliminated the use of expensive metal catalysts in building two C–N bonds.

  The synthesis of nitrogen-containing heterocycles from alkyl dihalides (ditosylates) and primary amines and hydrazines via a simple and efficient cyclocondensation in an alkaline aqueous medium that occurs under microwave irradiation is described. This improved greener synthetic methodology provides a simple C C and straightforward one-pot approach to the synthesis of a variety of heterocycles, such as substituted azetidines, pyrrolidines, piperidines, azepanes, N-substituted 2,3-diliydro-1H-isoindoles. 4,5-dihydropyrazoles, pyrazolidines, and 1,2-dihydrophthalazines.
