Metal-mediated allylation of enzymatically oxidized methyl α-d-galactopyranoside

Carbohydr. Res. 345 , 2610-5, (2010)

The C-6 unit of methyl α-D-galactopyranoside was selectively modified by combining enzymatic oxidation with an indium-mediated allylation reaction. The Barbier-Grignard type reaction, where a carbonyl...
