  Highly Stereoselective Brønsted Acid Catalyzed Synthesis of Spirooxindole Pyrans

  摘要：

  A Bronsted acid-catalyzed Prins-type cyclization sequence to construct spirooxindole pyrans in high yields and excellent diastereoselectivity has been developed. The combination of a beta-hydroxy dioxinone fragment and isatin dimethyl acetal generate oxa-spirooxindoles efficiently. These compounds are diversifiable scaffolds that tap into the rich chemistry of dioxinones.

  Two lactone formation reactions from 1,3-dioxin-4-ones having hydroxyalkyl group at the 6-position: Difference in ring opening and closure

  摘要：

  Two methods (A: ring opening to acylketenes followed by intramolecular ketene trapping and B: methoxide-mediated ring opening followed by cyclization of the hydroxy esters thus formed) have become available for the synthesis of lactones and/or cyclic ethers from 1,3-dioxin-4-ones having 1-approximately 4-hydroxyalkyl group at the 6-position. Mechanism and scope of both methods have been clarified.

  Functionalized acylfuranones have been prepared in a one-step procedure by thermal fragmentation of the corresponding dioxinones in the presence of hydroxy ketones in basic conditions. Multicomponent reactions also occur on addition of an aldehyde as a third reaction partner resulting in an expeditious access to cadiolide B and its analogues.

  efficient methodology for vinylogous aldol reactions based on SiCl4 catalysis. According to the nucleophilicity Mayr's scale, vinylogous aldol reaction of Chan's diene proved to be effective by using catalytic amount of SiCl4, without any other promoter. On the contrary, the SiCl4/Lewis base system has been conveniently exploited for the efficient and selective vinylogous reaction of less nucleophilic

  本文介绍了一种基于SiCl 4催化的乙烯基醇醛醇缩醛反应的新颖而有效的方法。根据亲核性迈尔（Mayr）规模，通过使用催化量的SiCl 4而不使用任何其他助催化剂，证明了陈氏二烯的乙烯基醇醛醇缩醛反应是有效的。相反，SiCl 4 / Lewis碱系统已被方便地用于较少亲核的Danishefsky's二烯和2-三甲基甲硅烷基氧基呋喃（TMSOF）的高效选择性乙烯基反应。实际上，许多路易斯碱（例如亚砜，甲酰胺和磷酰胺）已成功用作SiCl 4发起人。由2,2,6-三甲基-[1,3]-二恶英-4-酮衍生物衍生而来的TMSOF和甲硅烷基氧二烯需要化学计量的SiCl 4，而Chan和Danishefsky的二烯的乙烯基醇醛缩合反应在存在催化或亚化学计量的催化剂。

  日期：——

  A three step procedure for the synthesis of 6-substituted 4-hydroxy-2-pyrones 2 from aldehydes 1 is described. An acetoacetate equivalent 3 was added to the corresponding aldehyde (10 examples) in a vinylogous Mukaiyama aldol addition (72-99%). The intermediate alcohols 4 were oxidized to the ketones 5 using the Dess-Martin method (67%-quant.). A final thermal cyclization of compounds 5 yielded the title compounds 2 (61-92%; 40-85% overall).

  [reaction: see text] A scandium triflate catalyzed, diastereoselective cyclization between aldehydes and beta-hydroxy dioxinones has been discovered. This process capitalizes on the untapped nucleophilicity of the embedded enol ether within the dioxinone core.

  Vinylogous Mukaiyama-aldol reaction was realized by use of dioxinone-derived silyl dienol ethers and various aldehydes in the presence of highly catalytic amounts of bismuth triflate. The reaction proceeds rapidly and affords the corresponding β-hydroxy-1,3-dioxin-4-ones in very good to excellent yields (up to 98%).
