Synthesis of 6-substituted-3,4-dihydro-2H-1-benzopyran-2-ones(dihydrocoumarins) via palladium catalysed coupling reactions

6-Alkenyl, alkynyl, and aryl-3,4-dihydrocoumarins have been prepared from 6-bromo-3,4-dihydrocoumarin via palladium catalysed coupling reactions. 6-Carboalkoxy- and 6-keto-3,4-dihydrocoumarins have been obtained via palladium-catalysed carbonylations of 6
