摘要
Catalytic hydrogenation of the azide 8, prepared from D-ribonolactone, furnishes the 2-piperidone 9. Modification of the functional groups provides the homochiral 5-hydroxy-DELTA-3 piperidine-2-ones 20 and 21. Hydrolytic ring cleavage of 20 does not furnish 23. Treatment of 19 with barium hydroxide affords the benzylenolether 22 with isomerization of the double bond. Hydrolysis of 14 gives 5-amino-2R,3R,4R-trihydroxy-pentanoic acid 18.
