A facile synthesis of the title isocoumarins isolated from. Xyris indica was accomplished. Condensation of butanoyl chloride and 2-oxo-butanoyl chloride with 3,4-methylenedioxyhomophthalic acid afforded xyridin A and xyridinB respectively. Xyridin A was saponified to the corresponding keto acid which on reduction furnished the (±)-3,4-dihydro-6,7-methylenedioxy-3-propylisocoumarin. All of the synthesized
