[3+3] cycloaddition of azomethine ylides with nitrile imines was established to access unnatural cyclic amino acids containing 1,2,4-triazines. A series of 2,3,4,5-tetrahydro-1,2,4-triazine-5-carboxylates were obtained in moderate to excellent yields under mild reaction conditions.
建立了偶氮甲碱叶立德与腈亚胺的 [3+3] 环加成,以获取含有 1,2,4-三嗪的非天然环状氨基酸。在温和的反应条件下,以中等至优异的产率获得了一系列 2,3,4,5-四氢-1,2,4-三嗪-5-羧酸盐。
