  We demonstrate that configurationally stable anomeric stannanes undergo a stereospecific cross-coupling reaction with aromatic halides in the presence of a palladium catalyst with exceptionally high levels of stereocontrol. In addition to a broad substrate scope (>40 examples), this reaction eliminates critical problems inherent to nucleophilic displacement methods and is applicable to (hetero)aromatics

  highly stereospecific reaction of anomeric nucleophiles. First, methods for the preparation of anomeric stannanes have been developed and optimized to afford both anomers of common saccharides in high anomeric selectivities. We established that oligosaccharide stannanes could be prepared from monosaccharide stannanes via O-glycosylation with Schmidt-type donors, glycal epoxides, or under dehydrative

  糖类 C1 异头位置的立体选择性操作是制备性碳水化合物化学的核心目标之一。从历史上看，大多数与异头碳形成键的反应都集中在亲核试剂与带有离去基团的糖供体的反应上。在这里，我们描述了一种利用异头亲核试剂的高度立体特异性反应立体选择性合成 C-芳基糖苷的新方法。首先，已经开发并优化了制备异头锡烷的方法，以高异头选择性提供常见糖类的两种异头异构体。我们确定寡糖锡烷可以从单糖锡烷通过与施密特型供体、糖基环氧化物的 O-糖基化或在脱水条件下与 C1 醇制备。第二，我们确定了一组通用的催化条件，其中 Pd2(dba)3 (2.5 mol%) 和一个庞大的配体 (JackiePhos, 10 mol%) 控制了 β-消除途径。我们证明了糖基交叉偶联对具有单糖和低聚糖、脱氧糖、具有游离羟基的糖类、吡喃糖和呋喃糖底物的两种异头异构体产生始终如一的高异头选择性。在 Salmochelins（铁载体）和商业抗糖尿

  The stereoselective arylation of hydroxy protected 1,6-anhydro-beta-d-glucose with arylalanes to provide beta-C-arylglucosides is reported. Modification of triarylalanes, Ar3Al, with strong Bronsted acids (HX) or AlCl3 produced more reactive arylating agents, Ar2AlX, while the incorporation of alkyl dummy ligands into the arylating agents was also viable. Me3Al and i-Bu2AlH were found useful in the in situ blocking of the C3-hydroxyl group of 2,4-di-O-TBDPS protected 1,6-anhydroglucose. The utility of the method was demonstrated by the synthesis of the SGLT2 inhibitor, canagliflozin.
