Full Title

Heterocyclic compounds containing five-membered rings having two oxygen atoms as the only ring hetero atoms > having the hetero atoms in positions 1 and 3 > ortho- or peri-condensed with carbocyclic rings or ring systems > condensed with one six-membered ring > Methylenedioxybenzenes or hydrogenated methylenedioxybenzenes, unsubstituted on the hetero ring > with only hydrogen atoms, hydrocarbon or substituted hydrocarbon radicals, directly attached to atoms of the carbocyclic ring > Radicals substituted by carbon atoms having three bonds to hetero atoms with at the most one bond to halogen, e.g. ester or nitrile radicals
