Morphine derivatives having the formula
wherein:
A¹ represents -O-, -S-, -NR⁴- or -CHR⁵- ;
A² represents -O-, -S- or -NR⁴- ;
R¹ represents C₁-C₄ alkyl, C₁-C₄ alkenyl or cycloalkylmethyl;
R² represents H, C₁-C₆ alkyl, C₁-C₆ alkenyl, C₁-C₈ acyl or C₁-C₆ hydroxyalkyl;
one of X¹ and X² represents H and the other one is a group -A³-R³;
A³ represents -CH₂-, -CH₂CH₂-, -OCH₂-, -SCH₂-, -NR⁴CH₂-, -CO-, -NR⁴CO-, -SCO-, -SO₂-, -NR⁴SO₂-, -O-, -S- or -NR⁴-;
R³ represents an optionally substituted heterocyclic group;
R⁴ and R⁵ independently represent H or C₁-C₄ alkyl;
whereby the morphinan system may have a further unsaturation, in additon to the benzene ring.
These new morphine derivatives have improved analgesic and narcotic properties.
