WitrynaThe new imine ligand (E)-2,4,6- Me 3 C 6 H 2 CH 2 NCH t Bu ( 1 ) has been prepared from 2,4,6-trimethylbenzylamine and trimethylacetaldehyde. In this imine, the ortho -positions of the benzyl group are blocked by methyl groups, and there are no β-hydrogen atoms susceptible for imine–enamine rearrangement. Witrynagive imine ion with L-proline’s catalysis. Compound 4 then will react with the imine ion through nucleophilic addition to form intermediates 13. L-Proline activates the carbonyl acceptor 8 through hydrogen bond, which results to a higher active in-termediate 14. Later the proline-activated 14 reacts with in-termediates 13 to generate adducts 15.
