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-

The polyfunctional 2,3- and 3,4-o-bis(chloromethyl)pyridines 3, produced via cycloaddition of the oxazinones 2 with propargyl chloride and 1,4-dichloro-2-butyne, were used as precursors of various pyridine o-quinodimethane analogues. The 2,3- and 3,4-dime
