An expeditious synthetic protocol for polyhydroxyalkyl-pyridines and their 3-amino/mercapto-2-pyridinone analogues using unprotected aldoses as biorenewable resources is reported. The synthesis involves enol-driven Michael-type addition of lactones/ ketones to aldose-derived 1,3-oxazin-2-ones followed by decarboxylative ring transformation to yield various novel polyhydroxyalkylpyridines. This is a
