摘要:报道了钯催化芳基和杂芳基卤化物与新型硼酸化剂四(二甲氨基)二硼 [(Me 2 N) 2 B-b(Nme 2) 2] 的硼化反应.该方法是对先前报道的利用双硼酸 (Bba) 的方法的补充,因为某些底物在一组优化的反应条件下比另一组表现更好.由于四(二甲氨基)二硼是 Bba 和双(频哪醇)二硼(b 2 Pin 2)的合成前体,因此新方法代表了当前硼化方法的原子经济性和效率更高的方法.

标 题:Method for the synthesis of citric acid esters

摘要:The present invention discloses a targeted synthesis method for the synthesis of asymmetric monoesters and/or symmetrical diesters of citric acid through acidic esterification by using boric acid or a boronic acid as a catalyst. The boric/boronic acid simultaneously acts as a catalyst, as well as a 'protecting group' for the tertiary carboxylic acid, and therefore specifically only the asymmetric monoesters or symmetrical diesters are created.

标 题 :Preparation and uses of conjugated solid supports for boronic acids
发明人：HALL DENNIS G
权利人:UNIV ALBERTA
摘要:The invention provides novel solid supports comprising dihydroxyalkyl aminoalkyl and dihydroxyalkylaminobenzyl groups, and methods for making and using them. The supports are particularly useful for immobilizing and derivatizing functionalized boronic acids for use in solid phase synthesis, such as those used in combinatorial chemistries. The compositions and methods of the invention are also useful as scavenger solid supports, e.g., in solution-phase parallel synthesis of small molecule libraries, and for use in resin-to-resin transfer reactions via phase transfer of solid supported boronic acids under both aqueous and anhydrous conditions. The methods of the invention provide convergent solid-phase synthesis of symmetrically or unsymmetrically functionalized compounds, such as biphenyl compounds. Also provided are synthesizer devices, e.g., semiautomated parallel synthesizers.

摘要:Lamellarins are prepared using a solid phase synthesis. In a first aspect, the process includes a step as follows: Formula (I) where R 1 to R 15 are as defined, and X is halogen, provided that one of R 2 , R 3 or R 4 is immobilised to a resin. In a second aspect, the process includes a step as follows: Formula (II) where R 1 ′ to R 5 ′, R 11 ′ and R 13 ′ are as defined, X 1 and X 2 are halogen, M is a metal function and PG is an amino protecting group, provided that one of that R 2 ′, R 3 ′ or R 4 ′ is immobilised to a resin.
