The reaction of an open-chain analogue of Reissert compound hydrofluoroborate salt with ethyl acrylate does not give a [4+2] cycloadduct as previously described, but a [3+2] cycloadduct which evolves to a 2-pyridone 15.
## The reaction of the hydrofluoroborate salt of an open-chain The [3 + 2] cycloadducts 13 evolve via a rearrangementcondensation sequence to give a substituted 2-pyridone analogue of a Reissert compound with some Ξ±,Ξ²-ethylenic esters does not give a [4 + 2] cycloadduct, as previously derivative 1
