Abstract
Compounds consisting of esters of 4-hydroxy-2,9-dioxatricyclo[4.3.1.0.sup.3,7 ] decane having the formulae: ##STR1## in which formulae R.sub.1 is an alkyl radical having at most 4 carbon atoms, one of the radicals R.sub.2 and R.sub.3 is hydrogen and, when R.sub.2 is a hydrogen radical, R.sub.3 is a carbamyloxy radical and, when R.sub.3 is a hydrogen radical, R.sub.2 is a carbamyloxy, or an alkanoyl radical having at most 5 carbon atoms, the said carbamyloxy radical having the formula --OCONHR in which R is a hydrogen allyl, phenyl, cyclohexyl or an alkyl radical having at most 4 carbon atoms. The compounds are useful as sedatives and narcotics and can be produced by several different processes.
