We describe a method for obtaining various allylic, benzylic, and glucosyl 2,2,2-trichloroacetimidates (TCAIs) as stainless liquids or solids at the crude stage. The general synthetic method for the preparation of TCAIs often leads to stained products, and further purification of crude TCAIs causes decomposition due to their instability. In the described method, we use a solvent that barely dissolves
我们描述了一种在原油阶段以不锈钢液体或固体形式获得各种烯丙基、苄基和葡萄糖基 2,2,2-三氯乙酰亚胺 (TCAI) 的方法。制备 TCAI 的一般合成方法通常会导致产品染色,而粗 TCAI 的进一步纯化由于其不稳定性而导致分解。在所描述的方法中,我们使用几乎不溶解反应物的溶剂,提供不锈钢和足够纯的 TCAI,无需纯化步骤。此外,反应混合物在开始时是混浊的,在结束时是清澈的,这使我们能够直观地监测反应的进程。
