    摘要: The invention provides a process for the N-alkylation of normorphinan compounds to produce N-alkylated morphinan compounds. In particular, the process relates to the alkylation of a normorphinan compound by a carboxaldehyde in the presence of a reducing agent to form an N-alkylated morphinan.
