In this paper, first graphene oxide catalyzed one-pot three-component green synthesis of 1,3- thiazolidin-4-one using amine, aldehyde and mercapto acetic acid in water has been reported. The reaction is affected via sequential C-N and C-S bond formation and ring transformation reactions leading to thiazolidin-4-ones formation. The use of water as solvent at room temperature, good to excellent yields
在本文中,已经报道了首先使用胺,醛和巯基乙酸在水中氧化一氧化石墨烯催化一锅三组分绿色合成1,3-噻唑烷-4--4-酮。该反应受相继的CN和CS键形成以及环转化反应的影响,导致噻唑烷-4-酮的形成。在室温下使用水作为溶剂,纯产品的收率好至极佳(75-92%),操作简便是所设想方案的主要特征。氧化石墨烯催化剂非常温和,有效,并且在重复使用五次后,大部分活性得以保留。
