Novel cyclohexenone derivatives, which are shown by the general formula ##SPC1## Wherein each of R.sup.1 and R.sup.2 represents a hydrogen atom, lower alkyl or phenyl group; one of R.sup.3 and R.sup.4 represents a hydrogen atom or lower alkyl group, and the other represents an unsubstituted or substituted phenyl, lower alkyl or aralkyl group, or R.sup.3 and R.sup.4, taken together with the adjacent nitrogen atom, form a 5 to 6-membered heterocyclic ring; one of R.sup.5 and R.sup.6 represents a hydrogen atom or lower alkyl group, and the other represents a lower alkyl, phenyl or aralkyl group, or R.sup.5 and R.sup.6, taken together with the adjacent nitrogen atom, form an unsubstituted or substituted 5 to 6-membered heterocyclic ring, and their pharmaceutically acceptable salts, useful medicines such as analgesics.

The diyne amines CH3C = CC = CNR2 (R = CH3 or C2H5) have been synthesized with greater than 50% overall yields starting from 1,4-dichloro-2-butyne, the last step being a base-catalyzed isomerization of HC = CC = CCH2NR2.
