Abstract

Compound of the formula ##STR1## in which n stands for 0 or 1 and, where "n" stands for 0, a double bond is present as indicated by the chain line, and PA1 R represents a cyclohexyl radical, or a phenyl radical which may optionally be substituted in the p-position by a lower alkyl radical. The compounds are produced by reaction of methylethyl ketone substituted in the .beta.-position by R with cyanoacetic acid in the presence of a basic catalyst. The compounds are useful as perfumes.
