  Electroorganic Chemistry. 144. Electroreductive Coupling of Ketones with O-Methyl Oximes, N,N-Dimethylhydrazones, and Nitrones. A Convenient Route to Synthesis of .beta.-Amino Alcohol

  摘要：

  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.

• Preparation of Cyclic .ALPHA.-Hydroxy Ketones from .DELTA.- and .EPSILON.-Keto Acids Induced by the Generation of a Novel Acyl Anion Equivalent from the Carboxyl Group.

  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。
• Generation of acyl anion equivalents by in situ cathodic reduction of acyl tributylphosphonium ions anodically generated from tributylphosphine and carboxylic acids: preparation of α-hydroxy cycloalkanones from keto acids

  The preparation of α-hydroxy cycloalkanones from keto acids was effectively achieved by constant current electrolysis in the presence of Bu3P in an undivided cell under an N2 atmosphere, where the α-oxy ylides generated by the in situ cathodic reduction of acyl tributylphosphonium ions, formed anodically from tributylphosphine and carboxylic acids, seems to function as a novel acyl anion equivalent.

  通过恒电流电解法，在N2气氛下，使用Bu3P作为催化剂，在一个不分隔的电解槽中，成功实现了酮酸制备α-羟基环烷酮。在这个过程中，由酰基三苯基膦阴离子在阴极原位还原生成的α-氧叶立德，似乎扮演了一种新颖的酰基阴离子等价物的角色。这些酰基三苯基膦阴离子是由三苯基膦和羧酸在阳极形成的。

  chelating trivalent samarium and facilitating retroaldol-aldol-type equilibria in the product. In this latter case, the strategic combination of chemoselective carbonyl addition and SmI(2)/Pd(0)-promoted cyclization provides ready and convenient stereocontrolled access to functionalized cyclopentanols from unprotected 1,5-dicarbonyl starting materials. The analogous formation of cyclohexanols is limited by

  描述了炔丙基酯和羰基化合物之间的SmI（2）/ Pd（0）促进的分子内偶联。反应得到高炔丙基环烷醇产物。当使用酮作为羰基组分时，环戊醇以高收率形成，但是发现醛在这些反应中不是合适的伙伴。与相邻的功能化四元中心有效地形成产物特别引人注目。这些环化反应在新生成的炔丙基和甲醇立体异构中心附近具有低非对映选择性，除非这两个中心是季铵盐或存在能够螯合三价sa并促进产物中逆醛醇-醛醇型平衡的基团。在后一种情况下，化学选择性羰基加成和SmI（2）/ Pd（0）促进的环化的战略组合，提供了从不受保护的1,5-二羰基起始原料中轻松便捷地立体控制官能化环戊醇的方法。环己醇的类似形成受到环化产率低和缺乏立体选择性的限制。

  formed in high yield and are easily purified. The method has also been extended to the synthesis of fused N-phenylazabicyclics from 2-(3-oxo-propyl)cycloalkanones. A high degree of diastereoselectivity for the trans-fused product is observed in substrates having an ester group α to the cycloalkanone carbonyl. Bicyclic precursors lacking this ester group give mixtures of cis and trans products. Finally

  通过分别在4-和5-氧醛的存在下催化还原硝基苯来合成N-苯基取代的吡咯烷和哌啶。该方法包括还原芳族硝基以得到N-苯基羟胺或苯胺，然后用两个羰基官能团进行还原胺化。单环体系通常以高收率形成并且易于纯化。该方法还扩展到由2-（3-氧代-丙基）环烷酮合成稠合的N-苯基氮杂双环。在具有相对于环烷酮羰基的酯基为α的底物中，观察到对转熔产物的高度非对映选择性。缺少该酯基的双环前体可得到顺式和反式产品。最后，与以前的报道相反，我们证明了在这些反应中苯胺可以代替硝基苯。
