An improved method for producing apomorphine and derivatives thereof is provided. The method is a convenient 'one-pot' process, comprising the conversion of codeine into apomorphine without isolating the apocodeine intermediate. Use of water reactive scavengers, reagents that will react irreversibly with water, decreases side product formation and allows the use of milder reaction conditions. This one-pot synthesis of apomorphine from codeine provides a faster reaction with improved yields at temperatures lower as compared to conventional methods. The lower operating temperatures and less volatile reactants make the method particularly useful for large-scale manufacturing.

The present invention relates to methods for the synthesis of morphine, codeine, intermediates, salts and derivatives thereof. In preferred embodiments, the invention relates to methods for improving the efficiency, steroselectivity, and overall yield of said codeine and morphine related derivatives and intermediates thereof. The present invention relates to new codeine and morphine related derivative compositions.
There is provided an improved and convenient process for the synthesis of aporphines, such as apomorphine and apocodeine, by the rearrangement of the corresponding morphine or codeine derivatives. The use of a suitable water scavenger in an acid catalyzed rearrangement of the morphine derivatives unexpectedly results in a reaction temperature convenient for plant operation without sacrificing product. The method of the present invention also alleviates the cumbersome operations that were employed in the prior art to eliminate water from the reaction mixture at the elevated temperatures. This process is adaptable for the general preparation of other aporphines from the corresponding morphine congeners.
