    关于不饱和甲苯磺酰hydr的臭氧分解作为重氮羰基化合物的直接方法†
    摘要:
    描述了使不饱和甲苯磺酰with与O 3然后与Et 3 N反应生成1,4-和1,5-重氮羰基体系的范围和限制。甲苯磺酰肼是由甲苯磺酰肼与容易获得的δ和ε不饱和的α-酮酸酯缩合而成的,在前一种情况下会生成2-吡唑啉,而在后一种情况下会生成α-重氮-ε-酮酸酯,尽管末端烯烃会生成四氢哒嗪醇。使用臭氧分解-Et 3 N策略,来自环烯酮的甲苯磺酰hydr可生成在1位带有醛或酯官能团的2,5-和2,6-重氮酮。α-重氮醛偏爱s-反式构象,旋转势垒为74 kJ mol -1在25°C下通过NMR测定。这种一锅的臭氧分解/ Bamford–Stevens化学方法证明了甲苯磺酰hydr对臭氧的耐受性,以及随后添加的胺起着双重作用,将中间体甲苯磺酰直接转化为含有反应性重氮和酮官能团的产物;这样的加合物作为1,3-偶极环加成的环状羰基酰化物的前体特别有价值。

    名称:
    Inhibition of the mammalian .beta.-lactamase renal dipeptidase (dehydropeptidase-I) by Z-2-(acylamino)-3-substituted-propenoic acids
    摘要:
    The title enzyme deactivates the potent carbapenem antibiotic imipenem in the kidney, producing low antibiotic levels in the urinary tract. A series of (Z)-2-(acylamino)-3-substituted-propenoic acids (3) are specific, competitive inhibitors of the enzyme capable of increasing the urinary concentration of imipenem in vivo. Many of the compounds were prepared in one step from an alpha-keto acid and a primary amide. The optimum R2 groups are 2,2-dimethyl, -dichloro, and -dibromocyclopropyl. With R2 = 2,2-dimethylcyclopropyl (DMCP), a wide variety of R3 groups including alkyl, oxa- and thiaalkyl, and alkyl groups containing acidic, basic, and neutral substituents give effective inhibitors with Ki values of 0.02-1 microM and a range of pharmacokinetic properties. By resolution of enantiomers and X-ray crystallography, the enzyme-inhibitory activity of the DMCP group was found to reside with the 1S isomer. The cysteinyl compound 176 (cilastatin, MK-0791) has the desired pharmacological properties and has been chosen for combination with imipenem.

    compounds as oxygen nucleophiles. In particular, there are only a few reports on the oxy-Michael addition of the enol forms of carbonyl nucleophiles. In this study, we present the asymmetric cycloetherification of enols, which are generated in situ from enone-bearing ketones, using chiral bifunctional organocatalysts bearing amino and squaramide groups. This transformation chemo- and enantioselectively afforded
    用作碳亲核试剂的羰基化合物在合成有机化学中发挥了主导作用。然而,这些化合物作为氧亲核试剂的用途非常有限。特别是,关于羰基亲核试剂的烯醇形式的氧-迈克尔加成的报道很少。在这项研究中,我们使用带有氨基和方酸酰胺基团的手性双功能有机催化剂,介绍了烯醇的不对称环醚化,这些烯醇是由带有烯酮的酮原位生成的。这种转化化学和对映选择性地提供了二氢吡喃衍生物,这是合成聚糖的核心结构。
