Abstract
A new series of (2Z,2′E)-dimethyl 2,2′-[(2Z,2′Z)-3,3′-(alkanediyl)bis(4-oxo-2-iminothiozolidin-3-yl-5-ylidene)]acetates has been synthesized by the reaction of N,N″-(1,ω-alkanediyl)bis(N′-organylthiourea) derivatives with dimethyl acetylenedicarboxylate. The structures were established by spectroscopic data, elemental analyses, and single crystal X-ray crystallography. A rationale for the formation of the products is presented.
摘要 通过二甲基乙炔二羧酸酯与N,N''-(1,ω-烷烃二基)双(N′-有机硫脲)衍生物的反应,合成了一系列新型(2Z,2'E)-二甲基2,2'-[(2Z,2'Z)-3,3'-(烷烃二基)双(4-氧代-2-亚氨基噻唑烷-3-基-5-亚基)]乙酸酯。通过光谱数据、元素分析和单晶X射线晶体学确立了其结构。本文还提出了产物形成的合理性解释。
