Buprenorphine (5j) and diprenorphine (5k) were synthesized from N-formyl-northebaine (1c) and N-benzyl-northebaine (1d) via new intermediates.N-cyclopropylmethyl-dihydronorthevinone 3d is a suitable compund for the synthesis of both 5j and 5k.We carried out detailed (1)H- and (13)C-NMR analysis of the new compounds. Key words: Buprenorphine; diprenorphine; rotamers, N-CHO; morphinane derivatives; alkaloids.
