The research project presented in this book deals with the development of the alkylation of protected aldimines using organoaluminium and organozinc compounds as alkylating agents. To this end, efforts have been focused into the methylation reaction using trimethylaluminium and dimethylzinc. The identificaton of suitable metal catalysts as well as diphosphine ligands was carried out by means of extensive high throughput screening. A preliminary screening of a range of aldimines bearing different protecting groups aimed at selecting the most interesting substrate. The diphenylphosphinoyl (dpp) ...
