三个关键美拉德风味化合物的新的短期和通用合成方法:2-乙酰基-1-吡咯啉,6-乙酰基-1,2,3,4-四氢吡啶和5-乙酰基-2,3-二氢-4 H -1,4 -噻嗪
摘要:
一种新的合成路线,主要用于开发三个关键的美拉德风味化合物,即2-乙酰基-1-吡咯啉,6-乙酰基-1,2,3,4-四氢吡啶和5-乙酰基-2,3-二氢-4 H -1,开发了4-噻嗪。该方法的关键步骤是氮杂杂环羧酸酯通过二甲基噻吨并进行甲基化反应,生成中间体乙烯基醚,该中间体被认为是标题化合物的优异且稳定的前体,因为对这些前体进行简单的酸性处理就足以使其释放。独特的美拉德风味。

expedient single-step synthesis of 5,6,7,8-tetrahydroindolizines has been achieved via the annulation of commercially available 2-formylpiperidine hydrochloride and 1,3-dicarbonyl compounds in THF in the presence of pyrrolidine and 4 Å molecular sieves. A variety of β-ketoesters, ketones, and amides participated in this annulation chemistry, affording the desired 5,6,7,8-tetrahydroindolizines in moderate to
