保利(quinoxaline.2 3。研制了含二烷基烷氧侧链及其螺旋螺杆。为了深入了解催化不对称合成中不对称螺旋诱导的细节，我们成功地控制了这些分子。制备了具有活性端基的二烷基（Diyl）s及其螺杆。感官可以通过附着小的手性分子来控制。此外，我们还建立了一种快速、简便的筛选溶剂的方法，以有效地诱导单个。在聚（喹啉2,3.二基）s侧链上引入芘基的手性螺旋骨架。

Poly(quinoxaline.2,3.diyl)s bearing alkoxy side chains were developed and their helical screw.sense were successfully controlled to gain insight into the details of asymmetric helix induction for catalytic asymmetric synthesis.Poly(quinoxaline.2,3.diyl)s having reactive terminal groups were prepared and their screw.sense could be controlled by attaching small chiral molecules. Furthermore, we have established a quick and simple method for screening solvents for the efficient induction of a single.handed helical backbone by introducing pyrenyl groups on the side chains of poly(quinoxaline.2,3.diyl)s.
