Lewis acid catalyzed diastereoselective vinylogous Mannich reaction induced by O-pivaloylated d-galactosylamine as the chiral auxiliary: Stereoselective synthesis of 6-arylpiperidin-2-ones

The diastereospecific formation of β-N-glycosidically linked α,β-unsaturated δ-aminocarbonyl derivatives, in the form of (S)-δ-amino-δ-arylpent-2-enoic ester, has been achieved in high yield via a vinylogous Mannich reaction, utilizing poly-O-pivaloylated

Highly efficient asymmetric vinylogous Mannich reaction induced by O-pivaloylated d-galactosylamine as the chiral auxiliary

The diastereospecific formation of β-N-glycoside-linked α-amino-2(5H)-furanone has been achieved with high yield via a vinylogous Mannich reaction. The reaction was performed by using O-pivaloylated galactosylamine 1 as a chiral template and ZnCl2·Et 2O as a promoter in Et2O. Imines 3 of aromatic compounds and trimethylsiloxyfuran 4 were converted to N-galactosyl α-amino-2(5H)- furanone 5, giving ratios of diastereomers higher than 20:1. This procedure provides rapid access to biologically important γ-butenolide derivatives.
