  Thiourea‐Promoted Cascade Dihalogenation‐Cyclization of Cyclohexadienone‐Containing 1,6‐Enynes

  摘要：

  AbstractOrganohalogens play an important role in the drug discovery and functional materials. However, the convenient preparation of organohalogens still remains a challenging task. Herein, we report a metal‐free cascade dihalogenation‐cyclization of cyclohexadienone‐containing 1,6‐enynes in a biodegradable solvent to generate the dibrominated cis‐tetrahydrobenzofuran‐5(4H)‐ones and cis‐dihydrobenzopyran‐6(5H)‐ones respectively bearing 1,4‐dibromobut‐1‐enyl subunit in trans‐trans and trans‐cis form. A subgram‐scale experiment and several downstream transformations are presented for elaborating the synthetic utility. Moreover, the potent anticancer activity is observed against MDA‐MB‐468 cells for the corresponding products.magnified image

  摘要：

  在本文中，我们报道了用于连接顺式-氢苯并呋喃的炔烃系环己二酮的高度非对映异构和区域选择性二卤代反应。有效地形成了一个碳-碳键和两个碳-卤素键，并生成了三个连续的立体中心。该反应通过顺-卤化钯，迁移插入，然后卤化阴离子对烯醇钯的亲核攻击而进行。

  generation of sulfonyl radicals from sulfonyl azides using visible light and a photoactive iridium complex in THF is described. This process was used to promote sulfonylative and azidosulfonylative cyclizations of enynes to give several classes of highly functionalized heterocycles. The use of THF as the solvent is critical for successful reactions. The proposed mechanism of radical initiation involves

  Herein we demonstrate a Pd(II)-catalyzed regioselective hydrocarbofunctionalization of unactivated alkenes. The σ-vinyl-palladium(II) intermediate generated by the trans-acetoxypalladation of alkynes was added across carbon–carbon double bond to realize an efficient hydroalkenylation protocol. Bidentate auxiliary 8-aminoquinoline controls the regioselectivity of the carbopalladation step and thereby

  在本文中，我们证明了未活化烯烃的Pd（II）催化区域选择性烃官能化。由炔烃的反乙酰氧基钯产生的σ-乙烯基钯（II）中间体跨碳-碳双键添加，以实现有效的加氢烯基化方案。双齿辅助8-氨基喹啉控制碳钯步骤的区域选择性，从而控制氢化烯基化的区域选择性。另外，当使用在三个或四个位置上含有羟基的炔烃时，级联序列通过加氢烯基化反应随后导致分子内酰基迁移而生成1，6-二羰基化合物。

  A novel palladium‐catalyzed reaction involving an unusual nucleophilic attack on a palladium enolate was developed using a spiro‐bis(isoxazoline) (SPRIX) ligand. Treatment of alkynyl cyclohexadienone substrates with a Pd/SPRIX catalyst in acetic acid under an oxygen atmosphere furnished diacetoxylated benzofuranone derivatives in good yields. This cyclative diacetoxylation proceeded enantioselectively

  The first highly enantioselective rhodium-catalyzed cross-addition of silylacetylenes to cyclohexadienone-tethered internal alkynes has been achieved via a tandem process: regioselective alkynylation of the internal alkynes and subsequent intramolecular conjugate addition to the cyclohexadienones, affording the cis-hydrobenzofuran frameworks with good yields (up to 88% yield) and excellent enantioselectivities
