enyl)-3,5-diphenyl-4-hydroxythiazolium hydroxide and related alkenic systems, together with the corresponding prop-2-ynyloxy and cyanomethyloxy derivatives, undergo ready thermal intramolecular 1,3-dipolar cycloadditions giving stable 1 : 1-cycloadducts, substituted 4H-thieno[3,2-c]-, and 4H-thiazolo[4,5-c]-chromenes, respectively; the structure of one of these has been determined by X-ray crystallography
脱水-2-(2-烯丙氧基苯基)-3,5-二苯基-4-羟基噻唑鎓氢氧化物和相关的烯键体系与相应的丙-2-炔氧基和氰基甲氧基衍生物一起进行现成的分子内热1,3-偶极环加成反应,从而形成稳定的1:1-环加合物,分别被取代的4 H-噻吩并[3,2- c ]-和4 H-噻唑并[4,5- c ]-色烯;其中之一的结构已经通过X射线晶体学确定。
