  Asymmetric Synthesis of β-Amino Acid Derivatives Incorporating a Broad Range of Substitution Patterns by Enolate Additions to tert-Butanesulfinyl Imines

  摘要：

  Addition of Ti(Oi-Pr)(3) ester enolates to tert-butanesulfinyl aldimines and ketimines provided beta-substituted, alpha,beta- and beta,beta-disubstituted, alpha,beta,beta- and alpha,alpha,beta-trisubstituted, and alpha,alpha,beta,beta-tetrasubstituted beta-amino acid derivatives in high yields and with high diastereoselectivites. The N-sulfinyl-beta-amino ester products were further employed as versatile intermediates for both standard solution-phase and solid-phase synthetic transformations, including the synthesis of beta-peptide foldamers.

  Design, Synthesis and Antifungal Activity of the Novel Water-Soluble Prodrug of Antifungal Triazole CS-758

  摘要：

  CS-758 被选为临床试验的候选药物，但由于其水溶性不足以支持注射剂型，因此设计了磷酸酯前药。在这项研究中，描述了这些可注射前药的合成和评估。磷酸酯 17h 在水中可溶，并在水中及固态下稳定。17h 在人类肝微粒体中转化为 CS-758，并且在小鼠静脉（i.v.）给药后也能快速高效地转化为 CS-758。17h（i.v.）在小鼠血源性白色念珠菌感染模型的肾脏和小鼠肺部曲霉菌感染模型中减少了活细胞计数，效果与 CS-758（口服）相当或略优。

• Synthetic Strategies for the Synthesis and Transformation of Substituted Pyrrolinones as Advanced Intermediates for Rhazinilam Analogues

  The biaryl core structure of rhazinilam with its fixed dihedral angle is a pivotal element for its unique in vitro cytotoxic activity. Most of the related natural products are oxidized versions of rhazinilam. Replacing the sensitive pyrrole ring by a pyrrolinone ring is the basis of our initial strategy towards rhazinilam analogues. With this goal, variants of the sequence crossed Mukaiyama aldol reaction

  具有固定二面角的 rhazinilam 的联芳核心结构是其独特的体外细胞毒活性的关键因素。大多数相关的天然产物是氧化形式的 rhazinilam。用吡咯啉酮环代替敏感的吡咯环是我们对罗嗪类似物的初步策略的基础。为了这个目标，研究了与向山羟醛反应和施陶丁格反应交叉的序列变体。将适当取代的苯乙酮与 O-甲基 O-三甲基甲硅烷基乙烯酮缩醛反应以良好至极好的产率得到吡咯啉酮 8a 和 8b。这些中间体可以通过四个高产率步骤转化为吡咯前体 7a-c，其中包含构建 rhazinilam 环 A、B 和 C 所需的所有原子。我们的研究表明这些中间体缺乏稳定性。描述了针对该中心联芳基核结构的替代合成方法。

  CS-758 was selected as a candidate for clinical trials, but since its water-solubility was insufficient for an injectable formulation, phosphoryl ester prodrugs were designed. In this study, the synthesis and evaluation of these injectable prodrugs are described. Phosphoryl ester 17h was soluble in water, and was stable in both water and in a solid state. 17h was converted to CS-758 in human liver microsome and was also converted to CS-758 in rats after intravenous (i.v.) administration with good conversion speed and efficiency. 17h (i.v.) reduced the viable cell counts in kidneys in a murine hematogenous Candida albicans infection model and in lungs in a murine pulmonary Aspergillus fumigatus infection model, wherein the effects were comparable to or slightly superior to that of CS-758 (per os).
