α-Amino ketones were synthesized by a Meinwald rearrangement of biomass-based amino epoxides using copper(II) triflate as a catalyst. The regioselectivity of the rearrangement can be rationalized in terms of the reaction proceeding via the most stable carbocationic intermediate to give various α-amino α′-aryl ketones in moderate to good yields. This is an attractive method to prepare α-amino ketones
使用三氟甲磺酸铜(II)作为催化剂,通过基于生物质的氨基环氧化物的Meinwald重排合成α-氨基酮。重排的区域选择性可以通过最稳定的碳阳离子中间体进行反应来合理化,以中等至良好的收率得到各种α-氨基α'-芳基酮。这是使用良性且廉价的催化剂制备 α-氨基酮的一种有吸引力的方法。
