  摘要：

  Electroreduction of gamma and delta-cyano ketones in i-PrOH with Sn cathode gave alpha-hydroxy ketones and their dehydroxylated ketones as the intramolecularly coupled products. Guaiazulene, (-)-valeranone, polyquinanes, dihydrojasmone, methyl dihydrojasmonate, and rosaprostol have been synthesized by utilizing this electroreductive intramolecular coupling of gamma and delta-cyano ketones in one of the key steps. Similarly, electroreduction of a mixture of ketone and nitrile gave the corresponding intermolecularly coupled product. The product obtained by the electroreductive intermolecular coupling of (+)-dihydrocarvone with acetonitrile has been found to be the precursor of an effective chiral ligand for the enantioselective addition of diethylzinc to aldehydes.

  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。

• Cp2TiPh-coordinated cyano and ester groups as efficient ketyl radical acceptors in the reductive radical cyclization of γ- and δ-cyano ketones and δ-keto esters
  作者：Yoshihiko Yamamoto、Daisuke Matsumi

  DOI：10.1039/a800661j

  日期：——

  Cp2TiPh promotes the reductive radical cyclization of γ- and δ-cyano ketones and δ-keto esters to give α-hydroxycycloalkanones in moderate to good yields; the titanium reagent coordinates to both the ketone and the cyano or ester terminus, the LUMO of the cyano or ester group is thus lowered, and cyclization proceeds irreversibly without formation of the unstable iminyl or alkoxy radical intermediates.

  Cp2TiPh促进了γ-和δ-氰基酮及δ-酮酯的还原自由基环化，得到α-羟基环状酮，产率适中到良好；钛试剂与酮和氰基或酯末端均形成配位，氰基或酯基团的LUMO因此降低，环化过程不可逆进行，不会形成不稳定的亚胺或烷氧自由基中间体。

  The intermolecular coupling of a variety of ketones with some types of O-methyl oximes took place when a mixture of both components was electrochemically reduced in i-PrOH with an Sn cathode. The product, beta-methoxyamino alcohol was easily converted to beta-amino alcohol by simple reduction. A chiral ligand effective for the enantioselective addition of diethylzinc to an aldehyde was easily obtained from the product formed by the electroreductive coupling of (-)-menthone with O-methylacetaldoxime. The intermolecular coupling of a ketone with a N,N-dimethylhydrazone or nitrone was also promoted by the electroreduction. Furthermore, the electroreductive coupling of a carbonyl group with an intramolecular O-methyl oxime moiety gave the corresponding cyclized product stereoselectively.

  The reductive radical cyclization of cyanoketones was achieved using Cp2TiPh. The Ti(III) reagent was prepared by the sequential addition of i-PrMgCl and PhMgBr to commercial Cp2TiCl2 in this order and used effectively without isolation. The cyclization of the gamma- and delta-cyanoketones was performed in toluene at ambient temperature for several hours to give alpha-hydroxycyclopentanones and hexanones in moderate to good yields, respectively. The titanium reagent independently coordinates to both the carbonyl and cyano termini. As a result of lowering the LUMO of the cyano group upon coordination of the Ti(III) species, the irreversible cyclization successfully proceeds without formation of the unstable iminyl radical intermediate. The ester group can also be activated by the coordination of Cp2TiPh, and aromatic ketones with an ester group at the gamma position are cyclized to give the corresponding alpha-hydroxyketones.
