Dihydrocodeine is also the original member and chemical base of a number of similar semi-synthetic opiates such as [[acetyldihydrocodeine]], [[dihydrocodeine enol acetate]], [[dihydroisocodeine]], [[nicocodeine]], and [[nicodicodeine]]. | Dihydrocodeine is also the original member and chemical base of a number of similar semi-synthetic opiates such as [[acetyldihydrocodeine]], [[dihydrocodeine enol acetate]], [[dihydroisocodeine]], [[nicocodeine]], and [[nicodicodeine]]. | ||

Dihydrocodeine shares similar chemical structure to codeine, but lacks the double bond. This results in a much more stable chemical structure and also affects its metabolism. Dihydrocodeine can be synthesised from morphine by reduction of the 7,8-double bond. It readily converts to [[dihydromorphine]] with high yields (>95%). | Dihydrocodeine shares similar chemical structure to codeine, but lacks the double bond.
