标题:在无过渡金属的条件下,通过微波辅助方案对芳基和烷基硼酸进行高效的空气氧化
摘要:分子氧由于其优异的性能而成为最重要的绿色氧化剂.然而,分子氧的有效利用仍然是现代化学中的主要挑战.在此,我们报告了在无过渡金属条件下将硼酸空气氧化为苯酚和醇的快速,绿色和有效的微波辅助方案的开发.在koh和dmso的存在下,在微波辅助下可以高收率获得预期的酚和醇,并且在此过程中可以耐受各种官能团.值得注意的是,这种无过渡金属的方法代表了有机合成和绿色化学方面的突破,从而使硼酸氧化羟基化为酚和醇.

标题:Synthesis of 1,4-trans-polybutadiene using a lanthanide organic acid salt catalyst
发明人：LYNCH THOMAS J
权利人:BRIDGESTONE CORP
摘要:The invention provides a catalyst composition, comprising: (a) an organolithium compound; and, (b) an organic acid salt of lanthanide series element; wherein: (1) only components (a) and (b) are required to promote the synthesis of 1,4-trans-polybutadiene; (2) the ratio of component (a) to component (b) is selected to maximize formation of the trans structure of said 1,4-trans-polybutadiene; and, (3) components (a) and (b) are selected for enabling further diblock synthesis. The invention further contemplates a process for using the catalyst to synthesize 1,4-trans-polybutadiene and other polymers and copolymers having trans configuration in the conjugated diene monomer contributed units.

标 题:Methods for the solid phase synthesis of combinatorial libraries of benzimidazoles benzoxazoles benzothiazoles and derivatives thereof
发明人：LABORDE EDGARDO; MATSUMOTO YUKIHARU
权利人:TELIK INC
摘要:The present invention provides an efficient and versatile method for the synthesis and screening of combinatorial libraries of benzimidazoles, benzoxazoles, benzothiazoles, and derivatives thereof. In order to expedite the synthesis of large arrays of compounds possessing these core structures, a general methodology for solid phase synthesis of these derivatives is provided. Arrays of benzimidazoles, benzoxazoles, benzothiazoles, and derivatives thereof useful as peptidomimetics and for the identification of agents having antifungal, antiviral, antimicrobial, anticoagulant, and antiulcer activity, or use in the treatment of inflammation, hypertension, cancer, and other conditions can be prepared by this method.

标 题 :One pot synthesis of urea (meth)acrylates
发明人：BESTGEN SEBASTIAN; BEYER SILVIA
权利人:EVONIK OPERATIONS GMBH
摘要:A one-pot synthesis of polymerizable and acyclic urea (meth)acrylates, preferably mono(meth)acrylates, can be performed via in-situ synthesis of urea alcohols or amines followed by direct reaction with a (meth)acrylate reactive diluent. The urea alcohol/amine is obtained from isocyanates and alcohols, amines, or hydroxyamines. Subsequently, the reaction with the (meth)acrylate reactive diluent takes place and the urea (meth)acrylate is directly obtained either in solution with the reactive diluent, or as a pure material after removal of the reactive diluent.
