Definition of Acyliminium. Meaning of Acyliminium. Synonyms of Acyliminium

- one can acylate the iminium ion forming the intermediate N-acyliminium ion. The N-acyliminium ion is a very powerful electrophile and most aromatic ring...
- diastereomeric excess under different Petasis reaction conditions. Chiral N-acyliminium ion "starting materials" are generally prepared by in-situ dehydration...
- reaction and the Diels-Alder reaction. Niobium chloride can also generate N-acyliminium compounds from certain pyrrolidines which are substrates for nucleophiles...
- α-Hydroxyketones react with sulfene to form five-membered sultones. Forming acyliminium ions from α-hydroxyamides can be done using methanesulfonyl chloride...
- the presence of a Lewis acid, often with high diastereoselectivity. Acyliminium ions also parti****te in cycloadditions. These cations are generated...
