Abstract
An efficient and straightforward synthesis of furo[3,2-c]coumarins via the one-pot three component condensation of aromatic aldehydes, 4-hydroxycoumarin and -chloroketones in refluxing n-propanol is described. Pyridine or a mixture of AcOH and AcONH4 was used as a basic catalystFile in questo prodotto:
