N-Substituted N′-[6-methyl-2-oxido-1,3,2-dioxaphosphinino(5,4,-b)pyridine-2-yl]ureas have been accomplished by condensation of equimolar quantities of chlorides of various carbamidophosphoric acids (3) with 3-hydroxyl-6-methyl-2-pyridinemethanol (lutidine diol) (4) in the presence of triethylamine in dry toluene–tetrahydrofuran (1:1) mixture at 45–50°C. Their structures were established by elemental
N-取代的 N'-[6-methyl-2-oxido-1,3,2-dioxaphosphinino(5,4,-b)pyridine-2-yl]ureas 已通过等摩尔量的各种 carbamidophosphoric 氯化物的缩合完成酸 (3) 与 3-羟基-6-甲基-2-吡啶甲醇(二甲基吡啶二醇)(4),在三乙胺存在下,在干燥的甲苯-四氢呋喃(1:1)混合物中,45-50°C。它们的结构是通过元素分析、IR、1H NMR、13C NMR 和 31P NMR 光谱数据确定的。还评估了它们的抗真菌和抗菌活性。大多数这些化合物在试验中表现出中等的抗微生物活性。© 2003 Wiley Periodicals, Inc. 杂原子化学 14:509–512, 2003; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc
