Introduction Figure 2.6 Energy-minimized structure for host/guest complex 4/20 at the MM+ level. Trianglamine-Cu(OAc) 2 complex, obtained by stirring of trianglamine 27 (All-S) and Cu(OAc) 2 in dichloromethane (DCM) at room temperature, has been used as an efficient catalyst for the Henry reaction of aldehydes (i.e., 24) and nitromethane 25. 23 The β-hydroxynitroalkanes (i.e., 26) obtained by this approach form with high enantioselectivity (82-93% ee) under mild solvent free condition. The products from the reactions were obtained in the (R)-form (Figure 2.7). Figure 2.7 Enantioselective Henry reaction catalyzed by Trianglamine-Cu(OAc) 2 . 23 | P a g e
Introduction Trianglamine-Zn(R) 2 complexes have been recently used as efficient catalytic systems for asymmetric hydrosilylation of ketimines (i.e., 28) and ketones. The products from the catalytic reaction were obtained in high enantiomeric excess. 24,25 Addition of silane or a protic solvent was essential to facilitate the cleavage of the Zn-N bonds. Proposed mechanism for the hydrosilylation reaction is shown in Figure 2.8. 24 Figure 2.8 Asymmetric hydrosilylation of ketimine 28. 24 | P a g e
