Northebaine and N-allylnorthebaine have been synthesised from dihydronorcodeinone. O-Methylation of N-benzyloxycarbonyldihydronorcodeinone followed by hydrogenolysis with triethylsilane gave 8,14-dihydronorthebaine. Addition of methyl hypobromite and subsequent dehydrobromination gave norcodeinone dimethyl ketal, which underwent acid-catalysed elimination of methanol to yield northebaine, and thence
