The invention relates to novel [(5,6,9a-substituted-3-oxo-1,2,9,9a-tetrahydro-3H-fluoren-7-yl)-oxy]alkanoic and cycloalkanoic acid esters, analogs, the parent acids and their salts, and derivatives. These compounds are synthesized by methods selected from a number of synthetic routes depending on the particular structure, choice of intermediate or preferred reaction sequence. The compounds are useful in the treatment and prevention of injury to the brain and spinal chord due to accidents, ischemic stroke and hydrocephalus; compositions for such uses are also disclosed. |
