  A domino reaction of a β-ketoester, phenylethylamine and ethyl glyoxylate: leading to chiral tricarboxylate containing multiple stereocenters

  摘要：

  A new type of chiral tricarboxylate containing multiple stereocenters was synthesized via the one-pot reaction of a beta-ketoester. (S)-phenylethylamine, and ethyl glyoxylate. High yields and diastereoselectivities (up to 96:4 dr) were obtained under optimal conditions. The reaction of the chiral tricarboxylate with Zn(BH4)(2) gave chiral gamma-lactones in good yields With Lip to 92:8 dr. The structures and configurations of the new chiral tricarboxylates were characterized by X-ray diffraction analysis. (C) 2008 Elsevier Ltd. All rights reserved.
