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.

The diastereospecific formation of β-N-glycosidically linked α-aminophosphonic acids derivatives has been achieved with high yield via a Mannich-type reaction. The reaction was performed by using O-pivaloylated galactosylamine 1 as a chiral template and boron trifluoride diethyl etherate as a catalyst in THF. Imines 3 of aromatic compounds and diethyl phosphite were converted to N-galactosyl α-aminoalkylphosphonate 4, giving ratios of diastereomers higher than 19:1. This procedure provides a rapid access to biologically important galactosyl α-aminophosphonic acids derivatives.
