WebABSTRACT. Using an intramolecular nitrone cycloaddition and a Heck cyclization as the crucial transformations, a total synthesis of the racemic morphine alkaloid thebainone A … WebAbstract. The present invention provides methods for the conversion of thebaine to a morphine derivative, such as hydrocodone. Novel ketal intermediates of the conversion are provided. A one-pot procedure for the conversion comprises treating thebaine with an acid in the presence of a metal catalyst.
