ChemInform Abstract: Asymmetric Aldol Reaction of α‐Keto Esters with Isocyanoacetate and Isocyanoacetamide Catalyzed by a Chiral Ferrocenylphosphine/Gold(I) Complex.
摘要:
Biacetyl (Ia) and the α-keto esters (Ib) - (Id) react with N,N-dimethylisocyanoacetamide or methyl isocyanoacetate (II) in the presence of a diphenylphosphinoferrocene/gold(I) catalyst system to form the oxazolidines (III) as the main products, together with the diastereomers (IV).
