A simple and efficient 3 - step synthesis of α-dialkylamino - ketones 3 starting from aldehydes and sec.-amines is described. The unsymmetrically aminoketones are obtained as pure regioisomers via reaction of metalated α-aminonitriles 1 with aldehydes, followed by thermal HCN-elimination/tautomerization.
描述了从醛和仲胺开始的α-二烷基氨基-酮3的简单有效的3步合成。通过使金属化的α-氨基腈1与醛反应,然后进行热HCN消除/互变异构反应,可以得到纯的区域异构体形式的不对称氨基酮。
