Neuroactive benz[e]indene compounds ##STR1## are prepared by a total synthesis from the following three starting materials ##STR2##

Benz(epsilon)indene compounds

Novel tricyclic steriod analogs are disclosed which are 1H-benz[e]indene dodecahydro compounds that are useful for enhancing GABA-induced chloride currents at the GABA receptor/chloride ionophore complex and can be represented by the following structural formulas: ##STR1## wherein R.sub.1 =H or C.sub.1 -C.sub.4 alkyl or fluoroalkyl;
