  Synthesis of Fluorenone and Anthraquinone Derivatives from Aryl- and Aroyl-Substituted Propiolates

  摘要：

  Fluorenone derivatives were generated from aryl-substituted propiolates via a cobalt-catalyzed Diels-Alder reaction/DDQ-oxidation and Friedel-Crafts-type cyclization. Several functional groups are tolerated, and good to excellent overall yields (up to 89%) could be achieved. For the synthesis of anthraquinone derivatives, aroyl-substituted propiolates were applied in a zinc iodide catalyzed Die Is Alder reaction with 1,3-dienes. The subsequent DDQ oxidation and Friedel-Crafts-type cyclization led to symmetrical as well as some unsymmetrical anthraquinones in good to excellent yields of up to 87% over the three-step reaction sequence.

  concerns the asymmetric addition of methyl propiolate to aldehydes with 1,2-dimethoxyethane (DME) as additive and beta-sulfonamide alcohol titanium complex as a catalyst. The reactions proceeded under mild conditions and gave the highly functionalized chiral propargylic alcohols with high ee values and good yields. Differences between three types of ligands have also been discussed.

  这项工作涉及以1,2-二甲氧基乙烷（DME）为添加剂，以β-磺酰胺醇钛络合物为催化剂将丙酸甲酯不对称加成到醛中。反应在温和的条件下进行，得到具有高ee值和良好收率的高度官能化的手性炔丙醇。还讨论了三种类型的配体之间的差异。

  This work concerns the Mg(OMe)2 promoted allylic isomerization of γ-hydroxy-α,β-alkenoic esters with TMEDA as an additive. The isomerization proceeded under mild conditions and afforded γ-keto esters in high yield (up to 96%) within 2 h. Both (Z)- and (E)-γ-hydroxy-α,β-alkenoic esters were tolerated under the reaction conditions. This transformation involves the in situ formation of a dienolate intermediate

  这项工作涉及以TMEDA作为添加剂的Mg（OMe）2促进的γ-羟基-α，β-链烯酸酯的烯丙基异构化。异构化在温和的条件下进行，并在2小时内以高收率（高达96％）提供了γ-酮酯。在反应条件下，（Z）-和（E）-γ-羟基-α，β-链烯酸酯均被耐受。该转化涉及从容易获得的γ-羟基-α，β-链烯酸酯原位形成二烯酸酯中间体。该原位生成的二烯醇酯可以与苯甲醛反应并经历一种实用，有用的串联烯丙基异构化-羟醛反应，得到更多官能的化合物。
