  Enantioselective Synthesis of α,β-Disubstituted-β-amino Acids

  摘要：

  Highly diastereoselective and enantioselective addition of N-benzylhydroxylamine to imides 17 and 20-30 produces alpha,beta-trans-disubstituted N-benzylisoxazolidinones 19 and 31-41. These reactions proceed in 60-96% ee with 93-99% de's using 5 mol % of Mg(NTf2)2 and ligand 18. The product isoxazolidinones can be hydrogenolyzed directly to provide alpha,beta-disubstituted-beta-amino acids.

• Chemoselective Boron-Catalyzed Nucleophilic Activation of Carboxylic Acids for Mannich-Type Reactions

  The carboxyl group (COOH) is an omnipresent functional group in organic molecules, and its direct catalytic activation represents an attractive synthetic method. Herein, we describe the first example of a direct catalytic nucleophilic activation of carboxylic acids with BH3·SMe2, after which the acids are able to act as carbon nucleophiles, i.e. enolates, in Mannich-type reactions. This reaction proceeds

  羧基 (COOH) 是有机分子中无处不在的官能团，其直接催化活化是一种有吸引力的合成方法。在此，我们描述了用 BH3·SMe2 直接催化亲核活化羧酸的第一个例子，之后酸能够在曼尼希型反应中充当碳亲核试剂，即烯醇化物。该反应使用温和的有机碱 (DBU) 进行，并表现出高水平的官能团耐受性。硼催化剂对 COOH 基团具有高度化学选择性，即使存在其他羰基部分，如酰胺、酯或酮。此外，通过使用 (R)-3,3'-I2-BINOL 取代的硼催化剂，这种催化方法可以扩展到高度对映选择性的曼尼希型反应。

  Amino sulfonamide catalyst: A distal proton of the axially chiral amino sulfonamide (S)‐1 realized the opposite diastereoselectivity in Mannich and cross‐aldol reactions compared with that observed in proline‐catalyzed reactions. The reactions catalyzed by (S)‐1 proceeded smoothly to give the anti‐Mannich and syn‐aldol adducts in excellent enantioselectivity (see scheme).
