• Dynamic Kinetic Resolution and Desymmetrization Processes: A Straightforward Methodology for the Enantioselective Synthesis of Piperidines

  A straightforward procedure for the synthesis of enantiopure polysubstituted piperidines is reported. It involves the direct generation of chiral non-racemic oxazolo[3,2-a]piperidone lactams that already incorporate carbon substituents on the heterocyclic ring and the subsequent removal of the chiral auxiliary. The key step is a cyclocondensation reaction of (R)-phenylglycinol or other amino alcohols

  A facile synthesis of spirocyclic lactams starting from β-keto carboxylic acids via a one-pot cascade reaction involving a Curtius rearrangement and an intramolecular nucleophilic addition of the enol carbon to the isocyanate intermediate is reported. The same conditions have also been used for the generation of fused cyclic lactams with similar good yields. The synthetic value of this method has been

  日期：——

  An improved method for the transformation of keto acids into cyclic α-hydroxy ketones, induced by the electrochemical generation of a novel acyl anion equivalent from the carboxy group, has been developed. Both five- and six-membered rings were constructed by constant-current electrolysis of δ- and ε-keto acids in the presence of Bu3P using an undivided cell equipped with a graphite anode and a Pt cathode. Attempts to prepare four- and seven-membered ring carbocycles were unsuccessful. The electrochemical reaction was found to be highly stereoselective when cyclization took place onto cyclopentanone and substituted cyclohexanone rings. Stereochemical aspects of the formation of bicyclic products, especially those having a bicyclo[4.3.0]skeleton, are discussed.

  开发了一种改进的方法，通过电化学生成从羧基衍生出的新型酰基阴离子等价物，诱导将酮酸转化为环状α-羟基酮。通过在配有石墨阳极和铂阴极的无隔膜电池中，在Bu3P存在下对δ-和ε-酮酸进行恒流电解，构建了五元和六元环。尝试制备四元和七元环碳环未能成功。当环化反应发生在环戊酮和取代环己酮环上时，发现该电化学反应具有高度立体选择性。讨论了双环产物形成的立体化学方面，特别是具有双环[4.3.0]骨架的产物。
