  Asymmetric Synthesis of α-Amino Acids by Reduction of N-tert-Butanesulfinyl Ketimine Esters

  摘要：

  A highly regio- and diastereoselective reduction of various N-tert-butanesulfinyl ketimine esters with L-Selectride resulting in the formation of alpha-amino acids is reported. This method is quite general and also practical for the preparation of both enantiomers of aryl or aliphatic a-amino acids in high yields.

  An efficient palladium-catalyzed carbonylation reaction of readily available quaternary ammonium salts with CO is reported for the first time to afford arylacetamides and arylacetic acid esters via benzylic C–N bond cleavage. This protocol features mild reaction conditions under atmospheric pressure of CO, a redox-neutral process without an additional oxidant, and a broad substrate scope for various

• Antimicrobial toxicity studies of ionic liquids leading to a ‘hit’ MRSA selective antibacterial imidazolium salt

  Imidazolium salts can be classed as surfactants, detergents, ionic liquids, reagents, catalysts or solvents. A study of the toxicity and ecotoxicity of these salts yields valuable information for their use as pharmaceuticals as well as impact on the environment. Our approach to screen a series of chiral imidazolium salts for toxicity to bacteria and fungi, including clinical pathogen strains, has led to the identification of a ‘hit’ MRSA selective antimicrobial compound. Preliminary structure–activity-relationship (SAR) information (required position of L-phenylalanine and L-valine group) is also elucidated within this first generation of compounds. Conversely, most of the imidazolium salts were nontoxic (IC95 > 2 mM) to the 12 fungi strains and 8 bacteria strains screened, and we propose that they are suitable candidates for ‘green chemistry’ applications. Ecotoxicity studies (Biodegradation ISO 14593 ‘CO2 Headspace Test’) of two bromide ionic liquids containing L-phenylalanine residues indicate that these ionic liquids passed the test (>60% in 28 days) and classed as readily biodegradable.

  咪唑盐可分类为表面活性剂、洗涤剂、离子液体、试剂、催化剂或溶剂。对这些盐的毒性和生态毒性的研究，为其作为药物的使用以及对环境的影响提供了宝贵的信息。我们对一系列手性咪唑盐对细菌和真菌的毒性进行了筛选，包括临床病原菌株，从而鉴定出一种针对MRSA的选择性抗菌化合物。初步的结构-活性关系（SAR）信息（L-苯丙氨酸和L-缬氨酸集团所需的定位）也在这一代化合物中得以阐明。相反，大多数咪唑盐对筛选的12种真菌株和8种细菌株无毒（IC95 > 2 mM），我们提出它们是适合“绿色化学”应用的候选物质。生态毒性研究（ISO 14593生物降解“CO2顶空测试”）表明，含有L-苯丙氨酸残基的两种溴离子液体通过了测试（28天内>60%），被归类为易于生物降解。

  A range of N-alkoxycarbonyl- and N-carboxamido-oxaziridines has been prepared to test the effects of oxaziridine structure on yields of enolate amination product. Side-products arising from reaction of aldehyde-derived oxaziridines with base were identified, while a ketone-derived oxaziridine afforded moderate yields of amination product with stabilised carbanions.
