Abstract The pyrano-cyclisation of 4-hydroxy-(1-methyl)-1H-quinoline-2-one with 3-chlor-3-methylbut-1-yne, supposed to proceed via an ether or vinyl intermediate, is studied by alkylating different 4-hydroxyquinolines. The nine derivatives characterized favour the ether-pathway (“Späth type” chromene synthesis).
