The reactions of dialkyl acetylenedicarboxylates with various 2-oxo-acenaphthoquinylidene- and 4-acetyl[2.2]paracyclophanylidene-thiosemicarbazones were investigated. Using simple experimental procedures, 1,3-Thiazolidin-4-ones derived from acenaphthequinone or [2.2]paracyclophane were obtained as major products in good yields. In the case of allyl derivative of acenaphthoquinylidene-thiosemicarbazones
研究了乙炔二羧酸二烷基酯与各种 2-氧代-苊醌基和 4-乙酰基 [2.2] 对环亚基亚氨基硫脲的反应。使用简单的实验程序,从苊醌或 [2.2] 对环烷衍生的 1,3-噻唑烷-4-酮作为主要产品以良好的收率获得。在苊基并亚萘基-缩氨基硫脲的烯丙基衍生物的情况下,四甲基 5-(2-(((Z,E)-N-烯丙基-N'-(2-oxoacenaphthylen-1(2H)-ylidene)carbamohydrazonoyl) 的复杂结构)形成硫代)-1,2,3-三-(甲氧基羰基)-环丙基)-4-甲氧基-7-氧杂双环[2.2.1]庚-2,5-二烯-1,2,3,6-四羧酸酯。单晶 X 射线分析被用作确认合成化合物结构以及不同光谱数据(1H-NMR、13C-NMR、2D-NMR、质谱和元素分析)。讨论了所得产物的机理。
