标题:通过醇盐介导的有机硼酸酯脱硼基化直接合成叔膦
摘要:烷基硼的直接转化已成为创建碳-碳和碳-杂原子键的通用且强大的方法.然而,其在碳和磷形成中的潜在应用仍未得到探索.在这项研究中,我们提出了一种醇盐碱促进的反应系统,该系统能够通过选择性 C-B 键断裂对苄基有机硼酸酯和偕双(硼酸酯)进行脱硼基膦化.这种方法可以在温和条件下以非常好的收率合成有价值的叔膦.该方法的实用性和工业潜力通过操作简单性,广泛的基质范围和易于扩展性得到强调.

标题:Method for the synthesis of axially chiral organoboron compounds
发明人：PING YIFAN; CHE CHI-MING
权利人:LABORATORY FOR SYNTHETIC CHEMISTRY AND CHEMICAL BIOLOGY LTD
摘要:A highly efficient and atroposelective Rh-catalyzed [2+2+2] cycloaddition for the synthesis of axially chiral aryboron compounds is developed. The reactions of diynes and alkynylborons smoothly occur in an atom-economical manner, affording a variety of C—B atropisomers in excellent yields and enantioselectivities. The protocol features mild conditions, broad substrate scope, and good functional tolerance. The obtained C—B atropisomers show powerful synthetic applications in terms of producing novel chiral phosphine ligands.

标题:Low temperature synthesis of condensation polymers
发明人：OGATA NAOYA
权利人:GOODYEAR TIRE & RUBBER
摘要:Condensation polymers of high molecular weight, such as polyesters, polyureas, and polyamides, are usually prepared at temperatures of 200° C. or greater. However, by utilizing the catalyst systems of the present invention, condensation polymers can be synthesized at much lower temperatures. The polycondensation catalyst systems of the present invention are particularly useful for synthesizing aliphatic polyesters, such as polyethylene terephthalate, from dicarboxylic acids and aliphatic glycols. The present invention more specifically discloses a process for the synthesis of an aliphatic polyester comprising polymerizing at least one dicarboxylic acid with at least one aliphatic glycol in the presence of (1) at least one phosphorus containing compound which contains at least one trivalent or pentavalent phosphorus atom which is bonded directly to at least one phenyl group, (2) an acid acceptor, and (3) at least one halogenated organic compound. It is preferred to utilize a polymeric agent having bound acid acceptor groups as the acid acceptor in the process of the present invention.

标题:Chiral phosphinopyrrolidine compounds and their use for asymmetric synthesis of optically active compounds
发明人：ACHIWA KAZUO
权利人:ACHIWA KAZUO
摘要:New chiral phosphinopyrrolidine compounds of the general formula: (I) or (I') wherein R1 is a hydrogen atom, -COR, -COOR, -CONHR or -SO2-R where R is an alkyl or aryl group, R2 and R3 each represents independently an aryl group which may have a substituent or substituents, and R4 and R5 each represents independently an aliphatic or cycloaliphatic hydrocarbyl group which may have a substituent or substituents, as well as the use of these compounds as ligand for a metal complex catalyst for asymmetric synthesis of optically active compounds. The new chiral phosphinopyrrolidine compounds are useful ligands which attain both of high optical yield and high reaction efficiency in catalytic asymmetric reduction.
