  Synthesis and Antiallergic Activity of Dimethyl-2-(phenylcarbamoyl)ethylsulfonium p-Toluenesulfonate Derivatives

  摘要：

  The derivatives of dimethyl-2-(phenylcarbamoyl)ethylsulfonium p-toluenesulfonates were synthesized and evaluated for antiallergic activity. The 2,3-dihydroxyethoxy group was introduced to the phenyl ring from the standpoint of lipophilicity and electronic effects of substituent. The IgE-induced rat passive cutaneous anaphylaxis (PCA) was inhibited by oral administration of several substituted 2-[(4-propoxyphenyl)carbamoyl]ethyldimethylsulfonium p-toluenesulfonate derivatives. Among them (+/-)-2-[4-(3-ethoxy-2-hydroxypropoxy)phenyl]-carbamoyl]ethyldimethylsulfonium p-toluenesulfonate (1a, IPD-1151T) was found to possess considerable activity in the PCA test, and it was launched as Suplatast tosilate in Japan.

  acts as a heterogeneous catalyst for the ring-opening of epoxides with alcohols or anilines and the Friedel-Crafts reaction between N-benzylindole and crotonaldehyde at room temperature. Methanolysis of cyclic epoxides, styrene oxide, terminal aliphatic epoxides, and glycidyl ethers were carried out using the catalyst (0.4–6.8 mg/mmol of epoxide) and afforded the corresponding products in 53–97% isolated

  摘要 硫酸纤维素是通过将α-纤维素与浓硫酸在-10°C的乙醇中酯化而合成的。纤维素主要在纤维素的3、6和3、6位硫酸化。它在室温下用作环氧化物与醇或苯胺开环以及N-苄基吲哚和巴豆醛之间的Friedel-Crafts反应的非均相催化剂。使用催化剂（0.4–6.8 mg / mmol环氧）对环状环氧化合物，氧化苯乙烯，末端脂肪族环氧化合物和缩水甘油醚进行甲醇分解，在10分钟至24小时后，分离出的产率为53–97％，得到了相应的产物。硫酸纤维素已成功回收，并最多可重复使用3个催化循环，以使氧化苯乙烯与甲醇一起开环。
• Ring opening of epoxides with alcohols using Fe(Cp)2BF4 as catalyst
  作者：Geeta Devi Yadav、Surendra Singh

  日期：2014.7

  Fe(Cp)(2)BF4 is an efficient catalyst for the alcoholysis of aromatic, aliphatic, and cyclic epoxides giving excellent yields of the corresponding beta-alkoxy alcohols under ambient conditions. The methanolysis of styrene oxide using Fe(Cp)(2)BF4 as a catalyst (5 mol %) gave excellent yield of 2-methoxy-2-phenylethanol with complete regio-selectivity. The ring opening of cyclic epoxides gave 77-97% yields of trans-beta-methoxy alcohols, in 0.5-6 h. The use of 1,2-epoxyhexane and 1,2-epoxydodecane as substrates gave both regioisomers in excellent yields. The first order rate of reaction with respect to catalyst was observed for the kinetics of ring opening of 1,2-epoxyhexane with methanol. (C) 2014 Elsevier Ltd. All rights reserved.
