BEGIN:VCALENDAR VERSION:2.0 PRODID:-//hacksw/handcal//NONSGML v1.0//EN CALSCALE:GREGORIAN BEGIN:VEVENT LOCATION:Online DESCRIPTION:This presentation is dedicated to the modification of the Biginelli reaction for the synthesis of trisubstituted imidazoles from readily available acyclic N\, N-bis-nucleophiles\, 2-oxoaldehydes and 1\,3-dicarbonyl compounds. Most of the synthesized products were successfully used in the subsequent photocyclization reaction to form structurally interesting polycyclic molecules. The replacement of N\, N-bis-nucleophiles to ketenaminals allowed to carry out a similar process in a chemoselective manner to obtain a diverse library of fused polyheterocycles including pyrrolo[2\,1-b]thiazoles\, pyrrolo[1\,2-a]imidazoles and imidazo[1\,2-a] quinolines.
