摘要

The invention relates to novel N-(methoxymethyl -furylmethyl)-6,7-benzomorphanes and morphinanes, the acid addition salts thereof and to processes for their preparation. The novel compounds possess strong analgesic properties comparable to morphine, but do not possess certain of the side-effects associated with morphine. Processes for the production of the novel compounds are described and examples of certain of the novel compounds are given. Pharmaceutical compositions containing the novel compounds are described and exemplified.
