Enolates of chiral propionic acid amides were oxidatively dimerized with cupric salts or iodine with high simple as well as induced diastereoselectivity of up to 99:1. Intramolecular coupling of chiral dienolates of 1,7-heptanediamides led to α 1,2-disubstituted cyclopentane and a derivative of 1,2,6,7-cyclodecane tetracarboxylic acid.
手性丙酸酰胺的烯醇化物被铜盐或碘氧化二聚,具有极高的简单性和高达99:1的非对映选择性。1,7-庚二酰胺的手性二烯酸酯的分子内偶联导致α1,2-二取代的环戊烷和1,2,6,7-环癸烷四羧酸的衍生物。
