Abstract: Ene-sulfonamides, obtained from epoxy (terminal as well as internal) benzenesulfonamide and substituted chloro-acrylaldehydes, undergo Lewis acid (BF3.OEt2) catalysed cyclisation to afford azabicyclononene, tetrahydropyridinyl benzoate or tetrahydropyridine-carbaldehyde scaffolds depending on the... read more here.
