Abstract Reaction of tert-butyl 3-(2-hydroxyphenyl)-2-methylenepropanoate esters with aqueous KOH provides convenient and chemoselective one-pot access to 2H-chromene-3-carboxylic acids, the overall transformation involving tandem conjugate addition, hydrolysis and elimination steps. The methodology complements the chemoselective, acid-catalysed route to 3-substituted coumarins from the same substrates by switching the regioselectivity of cyclisation.
