The vicinal oxyamination of 1-substituted 1,2,3,6-tetrahydropyridines (I; R = PhCO, PhSO2, Me3COCO, MeOCO, MeCO, PhCH2) affords a mixture of the regioisomeric cis-hydroxycarbamates (II and III). The tert-butoxycarbonylamino and hydroxyl substituents for II and III assume the equatorial and axial orientations resp., irresp. of the substituent position. Acid hydrolysis of II– and III (R = PhCO) affords the cis-amino alcs. IV and V. The regiospecific oxyamination of 1-methyoxycarbonyl-1,2-dihydropyridine occurs at the 5,6-olefenic bond to yield the hydroxycarbamates VI and VII. Reduction of VI and VII with palladium on charcoal affords the same vicinal hydroxy and methoxycarbamates (VIII–XI) which may arise via an aziridine intermediate. In the experiment, the researchers used many compounds, for example, tert-Butyl 5,6-dihydropyridine-1(2H)-carboxylate (cas: 85838-94-4Recommanded Product: tert-Butyl 5,6-dihydropyridine-1(2H)-carboxylate).
