Popis: From oxazinones 4 , precursors for pyridine o-quinodimethane analogues are made accessible via cycloaddition with 1,4-dichloro-2-butyne and propargyl chloride. Subsequent 1,4-elimination of the polyfunctional o-bis(chloromethyl)-pyridines affords both 2,3- and 3,4-dimethylene compounds, which are trapped in situ with various dienophiles.
