摘要:已开发出一种在环境温度下用环己基碘对芳基镁卤化物进行铬催化的高度非对映选择性烷基化的简单方案.此外,这种不含配体的 Crcl2 能够使伯,仲和叔烷基卤化镁与容易获得的乙酸烯基酯进行有效的亲电烯基化.此外,这种与立体定义的烯基乙酸酯的化学选择性 C-C 偶联反应以立体保留方式进行.烷基碘化物和烯基乙酸酯上的各种官能团具有非常好的耐受性,从而以非常好的收率和高非对映选择性提供官能化的 Csp2-Csp3 偶联产物.详细的机理研究表明,原位生成的低价铬 (I) 物种可能是这些 Csp2-Csp3 交叉偶联的活性催化剂.

标题 :Process for the preparation of N-alkylated quaternary nitrogen containing aromatic heterocycles
发明人：PARADIES HENRICH H
权利人:MEDICE CHAM PHARM FABRIK PUTTE
摘要:The synthesis of 4-, 4-(1,1)-and 3,5-substituted N-alkyl-pyridinium salts as well as of 2-carboxamide substituted N(1,4)diazinium compounds are described. The N-surfactants obtained have a small critical micelle concentration (CMC) of 10-5 -10-7 Mol/Liter. These surfactants produce micells of different size and form depending on the nature of the anions. 4-(1,1)-substituted and 3,5-substituted N-alkyl-pyridinium components are capable of forming vesicles in equeous solutions of different forms and sizes. The N-surfactants synthesized can be used as pharmaceuticals.
