  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.

• Regiodivergent Reactions through Catalytic Enantioselective Silylation of Chiral Diols. Synthesis of Sapinofuranone A

  日期：2011.8.5

  catalyst, a regiodivergent silylation of chiral diols in cases where there is not a significant steric and electronic difference between the regioisotopic hydroxyl groups has been developed. This transformation allows for the conversion of racemic diols into regioisomeric, enantiomerically enriched, monosilylated products. The utility of this process is highlighted in the efficient enantioselective preparation

  通过使用基于氨基酸的咪唑催化剂，在区域同位素羟基之间没有显着空间和电子差异的情况下，已经开发了手性二醇的区域发散硅烷化。这种转化允许将外消旋二醇转化为区域异构的、富含对映异构体的单甲硅烷基化产物。该方法的效用在有用的合成中间体和天然产物皂基呋喃酮 A 的有效对映选择性制备中得到了强调。
