  An Asymmetric Route to Novel Chiral Cyclohexenones with Spiro-Connected Cyclopentenes. Further Utility of Chiral Bicyclic Thiolactams and the [3,3] Thio-Claisen Products

  摘要：

  Sequential allylation of chiral, nonracemic thiolactam 8 affords clean thio-Claisen [3,3] products ii. The stereoselectivity of the rearrangement was found to be on the order of 10-11:1, with the exo-endo products responsible for the mixture. Addition of hydride or methyllithium-cerium chloride gave clean addition to the thiolactam in the form of its iminium salts 12. Hydrolysis gave 4,4-dialkylcyclohexenones 16, which were cyclized to the cyclopentene derivatives 16 using Grubbs' catalyst.

  3-azabicyclo[4.1.0]heptanes in excellent yields and with high diastereoselectivities. These reactions constitute the first examples of intramolecular cyclopropanation of an alkene by a gold carbene generated by electrophilic ring opening of a cyclopropene in the presence of gold(I) chloride.

  烯丙基3,3-二甲基环丙烯基羰基醚或磺酰胺经历金催化的环异构化，从而以优异的收率和高的非对映选择性生成5-异亚丙基-3-氧杂-和3-氮杂双环[4.1.0]庚烷。这些反应构成了在氯化金（I）存在下通过环丙烯的亲电开环产生的金卡宾对烯烃进行分子内环丙烷化的第一个实例。

  The gold(I)‐catalysed cycloisomerisation of appropriately substituted 1,6‐cyclopropene‐enes proceeds through regioselective electrophilic ring opening of the three‐membered ring to generate an alkenyl gold carbenoid that achieves the intramolecular cyclopropanation of the remote olefin. This strategy allows straightforward, highly efficient and diastereoselective access to a variety of substituted

  金（I）催化的适当取代的1,6-环丙烯烯的环异构化过程通过三元环的区域选择性亲电子开环进行，以生成烯基金类胡萝卜素，从而实现远端烯烃的分子内环丙烷化。这种策略允许直接，高效和非对映选择性地获得各种取代的3-氧杂和3-氮杂双环[4.1.0]庚烷，以及双环[4.1.0]庚三-3-醇衍生物。由于所得环异构化产物中的异亚丙基可以进行臭氧分解，因此3,3-二甲基环丙烯表现出有趣的α-二氮杂酮代用品。

  DOI：10.1021/jo0625655

  日期：2007.3.1

  Enantioselective copper-catalyzed allylic alkylations were performed on allylic bromides with a protected hydroxyl or amine functional group using several Grignard reagents and Taniaphos L1 as a ligand. The terminal olefin moiety in the products was transformed into various functional groups without racemization, providing facile access to a variety of versatile bifunctional chiral building blocks.
