  Variable Strategy toward Carbasugars and Relatives. 2.¹ Diversity-Based Synthesis of β-d-Xylo, β-d-Ribo, β-l-Arabino, and β-l-Lyxo 4a-Carbafuranoses and (4a-Carbafuranosyl)thiols

  摘要：

  The silyloxy diene-based construction of carbasugars, previously exploited for the synthesis of four carbocyclic furanose and pyranose analogues, has been investigated further. By introducing a novel silylative cycloaldolization protocol and by adjusting a couple of minor transformations, the efficiency of this synthetic sequence was greatly improved. Through a series of lactone/thiolactone aldehyde cyclization precursors, four carbafuranoses (4a-carba-beta -D-xylofuranose, 4a-carba-beta -D-ribofuranose, 4a-carba-beta -L-arabinofuranose, and 4a-carba-beta -L-lyxofuranose) and four (carbafuranosyl)thiols [(4a-carba-beta -D-xylofuranosyl)thiol, (4a-carba-beta -D-ribofuranosyl)thiol, (4a-carba-beta -L-arabinofuranosyl)thiol, and (4a-carba-beta -L-lyxofuranosyl)thiol] were assembled. From this study, it was shown that these constructions tolerate a variety of precursors, and in many instances, they are suitable for scaling-up.
