Abstract: The regioselectivity of the intramolecular [2+2] cycloaddition reaction of acyl ketenes formed from metastable mesoionic 1,3-oxazinium-4-olates was investigated by experimental and theoretical methods. The ring opening of the mesoionic N -allyl-2-(2-arylvinyl)-1,3-oxazinium-4-olates led to the formation… read more here.
