Abstract
Homogeneous hydrogenation of two epimeric aldoses, D-glucose (D-Glc) a nd D-mannose (D-Man) was performed in water, with molecular hydrogen a nd by transfer hydrogenation catalyzed by [Ru-TPPTS] complex (TPPTS=tr isodium salt of tri(m-sulfophenyl)phosphine). Both method proved effec tive, and revealed D-Man as more reactive aldose. Hydrogen transfer ha s been studied with various hydrogen donors; the most effective, hut h ighly pH-dependent system has been found in Et(3)N/formic acid (azeotr opic mixture 2:5) as the source of hydrogen.
