Abstract

This study describes a C2-symmetric ligand comprising a central bipyridine-pinene-derived core and two functionalized diphenylmethanol subunits.[8′-(Hydroxy-diphenyl-methyl)-10, 10, 10′, 10′-tetramethyl-[5, 5′] bi [6-aza-tricyclo [7.1. 1.02, 7] undecyl]-2 (7), 3, 5, 2′(7′), 3′, 5′-hexaen-8-yl]-diphenyl-methanol 1 is an effective catalyst in the asymmetric ring opening (ARO) of meso-epoxides with PhSH and inductions of up to 69% ...
