  Stereoselective Hydrocoupling of [(1R)-exo]-3-exo-(Diphenylmethyl)bornyl Cinnamates by Electroreduction

  摘要：

  [GRAPHICS]The chiral auxiliary [(1R)-exo]-3-exo-(diphenylmethyl)borneol, synthesized from (1R)-(+)-camphor in three steps, was highly effective for the stereoselective hydrocoupling of its cinnamates by electroreduction. From the resulting hydrodimers, (3R,4R)-3,4-diaryladipic acid esters and (3R,4R)-3,4-diarylhexane-1,6-diols were synthesized in 87-95% ee.

• Photoinduced electron transfer reaction of cyclopropanone acetals with arylmethyl methanesulfonate: generation of β-keto radical species and application to C–C bond formation
  作者：Manabu Abe、Akira Oku

  日期：——

  The photoinduced electron transfer reaction of the cyclopropanone acetals 1 with arylmethyl methanesulfonates 4 or 10 as electron acceptors was found to generate a transient pair of radicals, the β-keto radical 3 and the arylmethyl radical, which underwent a novel carbon–carbon bond formation reaction at the sterically hindered β-position of the esters.

  研究发现，环丙酮缩醛 1 与作为电子受体的芳基甲基甲烷磺酸盐 4 或 10 发生光诱导电子转移反应时，会产生一对瞬时自由基--δ-酮自由基 3 和芳基甲基自由基，这对自由基在酯的立体受阻δ位上发生了新的碳碳键形成反应。

  Cross dehydrogenative coupling of aldehydes with methanol was investigated under organocatalytic conditions based on the cooperation­ between N-heterocyclic carbene and eosin Y·Na as an organophotocatalys­t. The combined use of eosin Y·Na and hexachloro­ethane (C2Cl6) was the effective method for the oxidative esterification of various aldehydes, because the oxidation steps are promoted by two pathways

  基于N-杂环卡宾与曙红Y·Na作为有机光催化剂的协同作用，在有机催化条件下研究了醛与甲醇的交叉脱氢偶联。曙红Y·Na和六氯乙烷（C 2 Cl 6）的联合使用是各种醛氧化酯化的有效方法，因为氧化步骤由与活化光催化剂和C 2 Cl 6相关的两条途径促进。相比之下，曙红 Y·Na 和溴三氯甲烷 (BrCCl 3 ) 的联合使用仅对简单的肉桂醛衍生物的氧化酯化有效，其中 BrCCl 3促进作为溴化试剂向自由基中间体的氧化。
