Organoaluminum reagents for selective reactions

Abstract

With the aid of selected examples an overview is given of the development trends in highly discriminative reactions using organoaluminum compounds. 1) Bulky organoaluminum reagent, methylaluminum bis(2,6-di-tert-butyl-4-alkylphenoxide) has been successfully utilized for stereoselective activation of carbonyl moiety. 2)Development of some chiral Lewis acid catalysts is described. These catalysts are utilized for asymmetric cyclization and hetero-Diels-Alder reaction. © 1988 IUPAC
