Highly stereospecific Mo(VI)-mediated synthesis of d-glycero-l-galacto-octulose
摘要:
A convenient, practical synthesis of D-glycero-L-galacto-octulose from a 2-C-(hydroxymethyl) branched-chain aldose, utilising the catalytic effect of molybdate ions is presented. 2-C-(Hydroxymethyl)-D-glycero-L-talo-heptose (obtained by elaboration of the appropriately protected aldose) gives access to an eight-carbon sugar in a single step through stereospecific isomerisation. The structure of the final product was determined by NMR spectroscopic analysis and theoretical calculations. (C) 2002 Published by Elsevier Science Ltd.
