Abstract: A method for preparing α-keto acids, especially α-ketomethionine, and/or derivatives thereof, whereby an aldehyde is reacted with thiols to give a corresponding dithioacetal, the dithioacetal formed, is reacted with an electrophile in the presence of a strong base, and the resulting α,α-(dithio)carboxylic acid is solvolyzed with acid-catalysis to release thiol and give the α-keto acid or a derivative thereof. Umpolung of aliphatic or aromatic aldehydes is effected by reaction with thiols.
Abstract translation: 一种制备α-酮酸,特别是α-酮基甲硫氨酸和/或其衍生物的方法,其中醛与硫醇反应,得到相应的二硫缩醛,形成的二硫缩醛与亲电子试剂在强碱存在下反应, 所得的α,α-(二硫代)羧酸用酸催化溶剂分解,释放硫醇,得到α-酮酸或其衍生物。 通过与硫醇反应来实现脂族或芳族醛的沸腾。
