Abstract

Abstract It is known that the rates and stereochemical outcomes of epoxidations and cyclopropanations using a metallosalen (salenH 2: N, N′-bis (salicylidene) ethylene-1, 2- diamine) complex as catalyst are affected by a trans effect of the apical ligand of the complex. By taking into consideration this trans effect, we have synthesized optically active pentadentate salen ligands bearing an imidazole or pyridine derivative as the fifth ...
