N-芳基-N′-(3,4,5-三甲氧基苯基)羰基脲类化合物的合成

Synthesis of N-Aryl-N′-(3,4,5-tirmethoxybenzoyl)urea Compounds

从3,4,5-三甲氧基苯甲醛出发,经过几步反应得到3,4,5-三甲氧基苯基羰基异氰酸酯;3,4,5-三甲氧基苯基羰基异氰酸酯再与芳胺反应,得到6个未见文献报道的N-芳基-N-′(3,4,5-三甲氧基苯基)羰基脲类化合物,其结构经元素分析I、R1、HNMR确证。

3,4,5-Trimethoxybenzoylisocyanate was obtained by a series of reactions starting from 3,4,5-trimethoxybenzaldehyde. 3,4,5-Trimethoxybenzoylisocyanate reacted with respective arylamine to obtain six new N-aryl-N＇-（3,4,5-tirmethoxybenzoyl）urea compounds. Their structures were characterized by elemental analysis,IR and ^1HNMR.
