Abstract

(10) The Lewis acidity effect should be explored. A TiC4TTi(OiPr), combination provides a better result for silicon reagents than TiCI, itself. This may be due to lower Lewis acidity of TiCI,(Oi-Pr)4-, which delays the bond-breaking process. ... Asymmetric Synthesis of Isoquinoline Alkaloids by Homogeneous Catalysis R. Noyori,* M.
