with active halo compounds afforded thiazoles 3–5. Moreover, reaction of compound 2 with acetic anhydride or dimethylformamide dimethylacetal gave N,N diacetyl 6 and dimethylamino derivatives 7, respectively. Cyclization of thiazole derivatives 3 with some arylidenemalononitriles yielded thiazolo[2,3‐d]pyrans 8–12. Multicomponent reaction of 2‐tosyloxybenzaldehyde (1) with urea, thiourea, or compound
用活性卤代化合物处理2-甲苯磺酰氧苄基硫代半脲(2),得到噻唑3 – 5。此外,化合物2与乙酸酐或二甲基甲酰胺二甲基缩醛的反应分别得到N,N二乙酰基6和二甲基氨基衍生物7。噻唑衍生物的环化3与一些arylidenemalononitriles得到噻唑并[2,3- d ]吡喃8 - 12。2-甲苯磺酰氧基苯甲醛(1)与尿素,硫脲或化合物2的多组分反应和乙酰乙酸乙酯或乙酰丙酮,得到嘧啶13 - 14。通过元素分析和光谱分析阐明了化合物的结构。
