  A Convenient Synthesis of Functionalized α-Methylidenebutano-4-lactams

  摘要：

  AbstractA concise synthetic approach to functionalized α‐methylidenebutanolactams has been developed. The synthetic strategy is based on the preliminary assembly of the lactam template equipped with appropriate functionalities. Subsequent installation of the methylidene by a metalation/alkylation/elimination sequence completed the elaboration of the racemic title compounds.

  Polyhydroxyalkanoate-based 3-hydroxyoctanoic acid and its derivatives as a platform of bioactive compounds

  摘要：

  A library of 18 different compounds was synthesized starting from (R)-3-hydroxyoctanoic acid which is derived from the bacterial polymer polyhydroxyalkanoate (PHA). Ten derivatives, including halo and unsaturated methyl and benzyl esters, were synthesized and characterized for the first time. Given that (R)-3-hydroxyalkanoic acids are known to have biological activity, the new compounds were evaluated for antimicrobial activity and in vitro antiproliferative effect with mammalian cell lines. The presence of the carboxylic group was essential for the antimicrobial activity, with minimal inhibitory concentrations against a panel of bacteria (Gram-positive and Gram-negative) and fungi (Candida albicans and Microsporum gypseum) in the range 2.8-7.0 mM and 0.1-6.3 mM, respectively. 3-Halogenated octanoic acids exhibited the ability to inhibit C. albicans hyphae formation. In addition, (R)-3-hydroxyoctanoic and (E)-oct-2-enoic acids inhibited quorum sensing-regulated pyocyanin production in the opportunistic pathogen Pseudomonas aeruginosa PAO1. Generally, derivatives did not inhibit mammalian cell proliferation even at 3-mM concentrations, while only (E)-oct-2-enoic and 3-oxooctanoic acid had IC50 values of 1.7 and 1.6 mM with the human lung fibroblast cell line.

• A Stereoselective and Practical Synthesis of (E)-α,β-Unsaturated Ketones from Aldehydes

  α,β-Unsaturated ketones can be prepared by reaction of differently substituted β-keto acids and aldehydes. The reaction is carried out under organocatalysis (β-alanine, 0.5 equiv.) and generates the enones with high E selectivity (>95 %). This version of the Verley–Doebner modification of the Knoevenagel reaction is a practical alternative to the classic Horner–Wadsworth–Emmons (HWE) reaction without

  α,β-不饱和酮可以通过不同取代的β-酮酸和醛反应制备。该反应在有机催化（β-丙氨酸，0.5 当量）下进行，并生成具有高 E 选择性（> 95 %）的烯酮。这个版本的 Knoevenagel 反应的 Verley-Doebner 修饰是经典 Horner-Wadsworth-Emmons (HWE) 反应的实用替代方案，不会形成高分子量副产物。该过程使用简单的试剂，可在符合原子经济原理的条件下应用于大规模合成。可以制备不同取代的脂肪族、芳香族或杂芳香族 α,β-不饱和酮。还描述了加氢甲酰化/Verley-Doebner Knoevenagel 伸缩过程的一个例子。
