  Regio- and stereoselective acylation of saturated carbocycles via Norrish–Yang photocyclization

  摘要：

  A regio- and stereoselective acylation of saturated carbocycles has been achieved through two-step reactions involving the Norrish-Yang photocyclization of 1,2-diketones and subsequent ring opening of the alpha-hydroxy-cyclobutanones. The C-H activation of the carbocycle proceeds regioselectively at vicinal to the diketone moiety resulting in stereoselective formation of cis-fused bicycles. The following C-C cleavage affords vicinally cis-acylated carbocycles. Predictability, generality, and practicality of the present strategy have been demonstrated using variously modified saturated carbocycles. (C) 2009 Elsevier Ltd. All rights reserved.

  烯丙基/炔丙基锆配合物的产生及随后的交叉偶联反应：多取代烯的简便合成

  摘要：

  炔丙基醚与Negishi试剂的β-醇盐消除反应在水解后会生成丙二烯和/或炔烃。产物的分布高度取决于起始炔丙基醚的取代方式。也就是说，芳基或烷基取代的炔丙基醚有利于丙二烯产物，而TMS取代的炔丙基醚则可提供炔烃。DFT计算显示，TMS组的大位阻效应和β效应均有利于炔烃产物，从而逆转了选择性。烯丙基/炔丙基锆中间体与芳基碘化物在Pd（PPh 3）4 / CuCl存在下的随后偶联反应为合成多取代的烯烯提供了一条直接途径。

  The β-alkoxide elimination reaction of propargylic ether with Negishi reagent leads to allenes and/or alkynes after hydrolysis. The product distribution is highly dependent on the substitution pattern of starting propargylic ethers; that is, aryl- or alkyl-substituted propargylic ethers favor the allene products, whereas TMS-substituted propargylic ethers afford alkynes. DFT calculations revealed that
