The conversion of pentoses to 3,4-dihydroxyprolines

The synthesis of two naturally-occurring isomers of 3,4-dihydroxyproline is reported. L-2,3-cis-3,4-trans-3,4-Dihydroxyproline was synthesized from L-arabinose in 10 steps and 31% overall yield. The same series of reactions was employed to convert L-xylos
