摘要

Abstract Amide coupling of (S p)-2-(diphenylphosphanyl) ferrocene-1-carboxylic acid with appropriate terminal amines mediated by 1-hydroxybenzotriazole and a carbodiimide affords multi-donor amides terminally functionalized with planar-chiral (S p)-2- (diphenylphosphanyl) ferrocen-1-yl moieties in good to excellent yields. Palladium catalysts based on these ligands efficiently promote asymmetric allylic alkylation of 1, 3- ...
