  Practical asymmetric synthesis of β-hydroxy γ-amino acids via complimentary aldol reactions

  摘要：

  Orthogonally protected chiral beta-hydroxy-gamma-amino acids can be accessed in >100 g quantities from readily available starting materials and reagents in three to four steps. These chiral synthons contain two adjacent stereocenters along with suitably protected functional groups (O-TBS, N-Boc) for downstream reactivity. Implementation of two existing aldol technologies allows rapid access to all possible stereo-isomers of 1. The guiding principles during reaction optimization were reaction scalability and operational efficiency. Conversion of the amino acids to a variety of chiral building blocks in one to two steps demonstrates their synthetic utility. (C) 2011 Elsevier Ltd. All rights reserved.

  Despite some stereochemical dependencies, the ring-forming reactions were optimized to proceed with good to excellent yields, providing a variety of skeletons ranging in size from 8- to 14-membered rings. Scaffolds resulting from the RCM pairing reaction were diversified on the solid phase to yield a 14 400-membered library of macrolactams. Screening of this library led to the discovery of a novel class

  应用基于羟醛的构建/耦合/配对 (B/C/P) 策略来生成立体化学和骨架不同的小分子的集合。在构建阶段，进行了一系列不对称的合成和反羟醛反应以产生 Boc 保护的 γ-氨基酸的四种立体异构体。此外，还生成了 O-PMB 保护的丙氨醇的两种立体异构体，以提供手性胺偶联伙伴。在偶联步骤中，通过偶联手性酸和胺结构单元合成了八种立体异构酰胺。随后将酰胺还原以生成相应的仲胺。在配对相中，采用了三种不同的反应来实现分子内成环过程：亲核芳香取代 (S(N)Ar)、Huisgen [3+2] 环加成和闭环复分解 (RCM)。尽管存在一些立体化学依赖性，但对成环反应进行了优化，以从良好到极好的产率进行，提供了大小从 8 到 14 元环的各种骨架。由 RCM 配对反应产生的支架在固相上多样化，以产生 14 400 成员的大环内酰胺文库。对该文库的筛选导致发现了一类新的组蛋白去乙酰化酶抑制剂，其表现出混合酶抑制
