Direct Regioselective Esterification at O-2 of beta-Cyclodextrin and Hydrolysis by Neighboring-group Participation 作者:Wang, ZZ (Wang, Zhi-Zhong)[ 1 ] ; Ma, XP (Ma, Xuan-Ping)[ 1 ] ; Wei, XG (Wei, Xiao-Gang)[ 1 ] E-JOURNAL OF CHEMISTRY 卷: 9 期: 3 页: 1562-1568 出版年: 2012 查看期刊信息 摘要 A simple and efficient strategy for direct regioselective esterification at O-2 of beta-cyclodextrin was developed by using the combination of N, N'-carbonyldiimidazole and carbonate buffer in 1,4-dioxane, which does not require large amounts of polar organic solvents such as DMF, toxic solvents such as CH3CN, or flammable bases such as NaH. Moreover, their hydrolyses by neighboring-group participation were observed. Mono-2-tosyl-beta-cyclodextrin was liable to epoxidation, while mono-2-(p-methylbenzoyl)-beta-cyclodextrin liable to isomerization. They had different mechanisms of hydrolysis. 关键词 作者关键词:beta-Cyclodextrin; Regioselective esterification; Neighboring-group participation; Hydrolysis KeyWords Plus  ERIVATIVES; CATALYSIS作者信息 通讯作者地址: Wang, ZZ (通讯作者) 隐藏增强组织信息的名称 Ningxia Med Univ, Sch Pharm, Ningxia Engn Res Ctr Hui Med Modernizat, Ningxia 750004, Peoples R China. 增强组织信息的名称 Ningxia Medical University 地址: 隐藏增强组织信息的名称 [ 1 ] Ningxia Med Univ, Sch Pharm, Ningxia Engn Res Ctr Hui Med Modernizat, Ningxia 750004, Peoples R China 增强组织信息的名称 Ningxia Medical University 电子邮件地址:wangzzsc@yahoo.com 基金资助致谢 基金资助机构 授权号 Natural Science Foundation of Ningxia Medical University XT201001 查看基金资助信息 出版商 HINDAWI PUBLISHING CORPORATION, 410 PARK AVENUE, 15TH FLOOR, #287 PMB, NEW YORK, NY 10022 USA 类别 / 分类 研究方向:Chemistry Web of Science 类别:Chemistry, Multidisciplinary 文献信息 文献类型:Article 语种:English 入藏号: WOS:000302358200060 ISSN: 0973-4945 期刊信息 Impact Factor (影响因子): Journal Citation Reports® 其他信息 IDS 号: 919VI Web of Science 核心合集中的 "引用的参考文献": 11 Web of Science 核心合集中的 "被引频次": 0 |
