在乙醇钠的催化下,4-[(三苯基膦叶立德)氨基]-2,3-二氢-3-苯基-2-硫代噻唑-5-羧酸乙酯(膦亚胺1)与芳香基二异氰酸酯和亲核试剂的双氮杂Wittig反应制得苯桥连的双[噻唑并[4,5-d]嘧啶-7(6H)-酮]衍生物,产率为56%~92%.产物结构经IR,1H NMR,MS和元素分析确证. Ethyl 4 - [(triphenylphosphoranylidene) amino] -2,3-dihydro-3-phenyl-2-thioxothiazole-5-carboxylate (phosphinimine 1) Benzene bridged bis [thiazolo [4,5-d] pyrimidin-7 (6H) -one] derivatives were obtained with bis-aza Wittig reaction of aromatic diisocyanates and nucleophiles in 56% ~ 92 %. The product structure was confirmed by IR, 1H NMR, MS and elemental analysis.
