reaction of trimethyl, triethyl, and triisopropylphosphites with 2-azido-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carbonitrile was developed and furnished spiro-triazaphosphole-oxide derivatives in ≈70 % yield. Contrary to these results, linear substituted phosphoramidates were obtained from the reaction of the azide with dimethyl, diethyl, and diisopropyl phosphites. N-Alkylamino- or 2-aminotetrahydr
摘要开发了亚磷酸三甲酯,亚磷酸三乙酯和亚磷酸三异丙酯与2-叠氮基-4,5,6,7-四氢苯并[ b ]噻吩-3-甲腈的新型高效共轭加成反应,并提供了约70%的螺-三氮杂膦氧化物衍生物让。与这些结果相反,从叠氮化物与亚甲基二甲基,二乙基和二异丙基亚磷酸酯的反应获得线性取代的氨基磷酸酯。N-烷基氨基-或2-氨基四氢苯并[ b还从前两个反应中以约10%的收率分离出了] thiophene-3-carbitrile。在这项工作的背景下,仅在质子化剂(乙醇)的存在下,才使六烷基磷三酰胺与相同的底物反应,得到相应的磷酸三酰胺。这三个反应平稳,干净地进行,并在室温下约6小时内完成。根据结构-活性关系,讨论了该产品的抗乳腺癌,抗结肠和抗前列腺癌细胞系药理评价结果,以定义铅化合物的发色团。 。 图形概要
