4-amino-2-(het)aryl/alkyl-5-functionalized thiazoles has been disclosed, utilizing aryl/heteroaryl/alkyl dithioesters as thiocarbonyl coupling partners in a modified Thorpe–Ziegler type cyclization. The reaction proceeds at room temperature, under mild conditions, in excellent yields, displaying broad functional group compatibility at 2 and 5 positions of thiazoles. This synthetic strategy has been further
已经公开了一种有效的、面向多样性的、4-氨基-2-(杂)芳基/烷基-5-官能化噻唑的一锅反应,利用芳基/杂芳基/烷基二硫酯作为改性索普-齐格勒型中的硫代羰基偶联伙伴环化。该反应在室温、温和条件下以优异的产率进行,在噻唑的 2 位和 5 位显示出广泛的官能团相容性。这种合成策略已进一步扩展用于高产率的一锅法构建两种高效微管蛋白聚合抑制剂,即 2-(het)aryl-4-amino-5-(3,4,5-trimethoxyaroyl) thiazoles .
