    • Abstract


      7-Hydroxy-5-methylcoumarin has been synthesised from orcylaldehyde by condensation with diethyl malonate and by subsequent removal of the carbethoxyl group. The compound obtained from orcinol and malic acid by the method of Pechmann has been shown to be identical with the above product and hence it is concluded that in this case orcinol exhibits reactivity of the β-position.
