- One-pot triflic anhydride-mediated synthesis of 1,2-disubstituted 2-imidazolines from N-(2-haloethyl)amides and amines
-
A one-pot synthesis of 1,2-disubstituted 2-imidazolines from N-(2-haloethyl)amides has been developed. The reaction affords high yields of diverse 1,2-disubstituted 2-imidazolines from triflic anhydride-mediated dehydration of amides followed by installat

4,5-Dihydroimidazolium salts 2, 3, and 4 were synthesized by carefully directed alkylation of 4,5-dihydroimidazoles 7 and 8. 2, 3, and 4 were deprotonated by sodium hydride to yield 2-alkylideneimidazolidines 1. 1H and 13C-NMR spectra allow to assign the
