Isocoumarins .
1-Isochromen-1-ones .
1H-2-Benzopyran-1-ones .
Compounds that differ from COUMARINS in having the positions of the ring and ketone oxygens reversed so the keto oxygen is at the 1-position of the molecule. .

Oxazoles .
1,3-Oxazolium-5-Oxides .
Munchnones .
1,3 Oxazolium 5 Oxides .
Five-membered heterocyclic ring structures containing an oxygen in the 1-position and a nitrogen in the 3-position, in distinction from ISOXAZOLES where they are at the 1,2 positions. .
