have been prepared using bis(oxazoline) building blocks either as nucleophiles or as electrophiles in coupling reactions with central aromatic units. This way, a great variety of pentadentate bis(oxazoline) ligands in diastereo- and enantiomerically pure form become readily available, which are useful for the construction of helical metal complexes with predetermined chirality.
使用双(恶唑啉)结构单元作为亲核试剂或亲电试剂,已制备了高度模块化的N,Y,Z,Y,N配体(Y = N,O,S; Z = N,NO,OH,OMe)与中心芳族单元的反应。这样,很容易获得非对映体和对映体纯形式的多种五齿双(恶唑啉)配体,其可用于构建具有预定手性的螺旋金属配合物。
