  Synthesis, resolution, and antiplatelet activity of 3-substituted 1(3H)-isobenzofuranone

  摘要：

  A series of 3-substituted-1(3H)-isobenzofuranone 6a-g and 7a-g were synthesized from phthalic anhydride. The compound 6a-g was resolved. The antiplatelet activities of these compounds were evaluated using in vitro experiment of platelet aggregation. The levels of antiplatelet activity were displayed as following sequence: l-isomer > dl-isomer > d-isomer, respectively. The alkylphthalide is more active than the corresponding alkenephthalide. All these compounds were less active than n-butylphthalide (NBP, 6c) and Aspirin (Asp). (c) 2007 Elsevier Ltd. All rights reserved.

  A triflic acid (TfOH) mediated sequential cyclization of ortho-alkynylarylesters and ammonium acetate (NH4OAc) was reported. The reaction took place via a Brønsted acid-mediated intramolecular cyclization of ortho-alkynylarylesters followed by an ammonium acetate participated substitution reaction, forming isoquinolin-1-ones as the major products. Different from most of the known synthetic methods

  报道了三氟乙酸（TfOH）介导的邻炔基芳基酯和乙酸铵（NH 4 OAc）的顺序环化。该反应通过布朗斯台德酸介导的邻位分子内环化反应进行-炔基芳基酯接着乙酸铵参与取代反应，形成异喹啉-1-酮为主要产物。与大多数已知的异喹啉-1-酮合成方法不同，所报道的反应不需要金属催化剂。在少数情况下，获得了区域异构体–异吲哚啉-1-酮与异喹啉-1-酮。还分离了中间体化合物-异色酮-1-酮和异苯并呋喃-1-酮。相互转化实验表明，在布朗斯台德酸诱导的邻炔基芳基酯分子内环化过程中形成的区域异构体。采用这种新方法，可以以中等收率制备天然产物ruprechstyril。

  Abstractmagnified imageA general and efficient copper(I)‐catalyzed cross‐coupling and heterocyclization reaction of terminal alkynes and β‐iodo‐α,β‐unsaturated acid derivatives has been developed under very mild conditions. This method provides easy access from good to excellent yields of a variety of 5‐ylidenebutenolides and 3‐substituted isocoumarins with excellent regio‐ and stereoselectivity. This procedure does not require the use of any expensive supplementary additives, and is palladium‐free.

  The coupling of o-bromobenzoic acid with terminal alkynes using 10% Pd/C-Et3N-CuI-PPh3 as a catalyst system leads to the synthesis of (Z)-3-alkylidenephthalides as the major product along with the traces of isocoumarin when the reaction was performed in 1,4-dioxane. The methodology afforded a range of compounds including (Z)-3-(4-(methylsulfonyl)benzylidene)isobenzofuran-1(3H)-one of potential pharmacological interest. (C) 2013 Elsevier Ltd. All rights reserved.
