Substituted 5H-dibenz[b,g]-1,4-oxazocines and related amino acids with antiinflammatory activity
During an investigation of the antiinflammatory properties of a number of tetracyclic derivatives of 6,8-dichlorodibenz[b,f]oxepin-10(11H)-one, the ring-expanded 1,3-dichloro-5H-dibenz[b,g]-1,4-oxazocine was prepared and found to be of considerable pharma
