  Doubly carbon-branched pentoses: synthesis of both enantiomers of 2,4-di-C-methyl arabinose and 2-deoxy-2,4-di-C-methyl arabinose using only acetonide protection

  摘要：

  An acetonide is the only protecting group used in the synthesis of both the enantiomers of 2,4-di-C-methyl arabinose and 2-deoxy-2,4-di-C-methyl arabinose via the enantiomeric 3-C-methyl-L-erythronolactone [from 2-C-methyl-D-ribono-lactone or D-ribose] and 3-C-methyl-D-erythronolactone [from D-tagatose Or L-ribose]. NMR studies on unprotected C-methyl arabinoses show that methyl branching significantly affects the ratios of pyranose and furanose forms present in aqueous Solution. (C) 2009 Elsevier Ltd.
