piperidine afforded the Michael type adducts 8, which on treatment with different substituted chalcones in the presence of piperidine gave the Michael adducts 9. Compounds 9 underwent reductive cyclization on treatment with SnCl2–MeOH to afford the title compounds 10. Structure of these compounds was established on the basis of IR, 1H NMR, 13C NMR and Mass spectral data. The title compounds 10a–j were evaluated
从3-甲基-4-硝基-5-苯乙烯基恶唑6合成了一系列新型的苯基亚甲基双-异恶唑并[4,5- b ] a庚因衍生物(10)。的反应6与3,5-二甲基-4- nitroisoxazole(7在哌啶,得到迈克尔加成物型)8,其用在哌啶的存在下不同的取代的查耳酮处理,得到的迈克尔加合物9。化合物9经过SnCl 2 -MeOH处理后进行还原环化,得到标题化合物10。这些化合物的结构是根据IR,1 H NMR,13 C NMR和质谱数据。评价了标题化合物10a – j的体外和体内抗癌活性。与标准药物顺铂相比,化合物10j具有良好的抗癌活性。
