Research Abstract

本研究では、立体配座の自由度を規制した共役ジエン構造に基づく螺旋不斉を基とする新規ジホスフィン配位子を設計し、その合成を行った。得られたラセミ体の化合物は、キラルHPLCにより熱的に安定な2つのエナンチオマーに分割することがでた。さらには、ジホスフィンオキシドを2つのエナンチオマーに効率良く分割する手法を見出した。一方、ジホスフィンオキシドのシランによる還元では炭素ーリン結合の開裂がおこり、目的とするホスフィンを得る事はできなかった。光学活性ジホスフィンオキシドを、不斉有機触媒としてアリルシランによる不斉アリル化に応用し、優れた不斉誘起能があることを見出した。
