Stereoselective hydrogenation of Wittigg products obtained readily (via the 3′-ketones) from 2′,5′-bis-O-(tert-butyldimethylsilyl)nucleosides provides efficient access to 2′,3′-fused γ-butyrolactone-nucleosides that can be coupled with 5′-amino-nucleosides (2-hydroxypyridine catalysis) to gi...
3-hydroxy-2-(2-phenylethyl)pyridineaminomethylationThe aminomethylation of 3-hydroxy-6-methyl- and 3-hydroxy-2-(2-phenylethyl)pyridines by secondary amines has been investigated. It was shown that like 2-alkyl-3-hydroxypyridine aminomethylation is directed primarily to position 6 and then 4 of ...

Two kinds of 3-hydroxypyridine-2(1H)-thiones were synthesized. The visible (VIS) spectroscopic analysis indicated that 3-hydroxy-1-methylpyridine-2(1H)-thione (4a) and 3-hydroxy-1-(2-hydroxyethyl)pyridine-2(1H)-thione (4b) formed stable 3:1 Fe(III) complexes. The stability constant of ...
3-[3-(Pyridin-2-yl)-4,5-dihydroisoxazol-5-ylmethyl]-1,3-benzothiazol-2(3)-one was synthesized with high regioselectivity by 1,3-dipolar cycloaddition of 3-allyl-1,3-benzothiazol-2(3)-one to pyridine-2-carbonitrile oxide generated from-hydroxypyridine-2-carboximidoyl chloride hydrochloride ...
