Abstract
Novel N-sec-alkyl derivatives of norcodeine and normorphine wherein the sec-alkyl group contains either four or five carbon atoms. Specifically included are those derivatives of norcodeine and normorphine wherein the sec-alkyl group is 2-butyl, 3-pentyl, .alpha.-methylallyl and .alpha.-methylcyclopropylmethyl. The normorphine derivatives having strong agonist potency combined with strong antagonist qualities and indicated low addiction potential. The norcodeine analogs are useful as intermediates in preparing the corresponding normorphine compounds.
