Rc. Fox et Pd. Taylor, Efficient syntheses of N-alkyl-3-hydroxy-2-methyl-4(1H)-pyridinones from carbohydrate precursors, SYN COMMUN, 29(6), 1999, pp. 989-1001
N-alkyl-3-hydroxy-2-methyl-4(1H)-pyridinohes can be synthesised in reasonab
le yield from either 1-(3-hydroxy-2-furanyl)ethanone or O-galactosylisomalt
ol. Since these carbohydrate precursors can be produced from the disacchari
de, alpha-D-lactose, a simple and inexpensive transformation into pyridinon
es is possible.
