Syntheses of Racemic Diaminosugar Derivatives Starting from 1,2-Dihydropyridines and from Nitrosobenzene

Racemic diaminosugars were easily obtained by a regio- and stereoselective three-step synthesis.In the first step, regiospecific hetero-Diels-Alder cycloadditions between 1,2-dihydropyridines 1a and 10 and nitrosobenzene led to bicyclic compounds 2a and 1

A FACILE THREE-STEP SYNTHESIS OF A RACEMIC 4,5-DIAMINO-4,5-DIDEOXY-α-D,β-L-LYXOPYRANOSE.

Diels-Alder cycloaddition of nitrosobenzene to 1-methoxycarbonyl-1,2-dihydropyridine led in high yield to the endocyclic hydroxylamine adduct 5.which was successively oxydized with potassium permanganate and hydrogenolyzed to give the new aminosugar 4,5-d
