Abstract

Abstract Compounds having the formula ##STR1## wherein R is an alkyl group having from 1 to 4 carbon atoms are produced by the condensation of the appropriate alkoxylated epoxide with diethyl malonate. The unsaturated compound is formed by the dealkoxylation of an alkoxylated compound. These compounds have attractive fruity-floral type odors and are useful as ingredients of compounded perfumery compositions. The invention also includes perfumery compositions containing at least one of said compounds.
