PREPARATION OF SUBSTITUTED MORPHINAN-6-ONES AND SALTS AND INTERMEDIATES THEREOF

The present invention is directed to processes for the synthesis of morphinan-6-ones and salts, intermediates, and analogs thereof.

Synthetic Opium Alkaloids and Derivatives. A Short Total Synthesis of (+/-)-Dihydrothebainone, (+/-)-Dihydrocodeinone, and (+/-)-Nordihydrocodeinone as an Approach to a Practical Synthesis of Morphine, Codeine, and Congeners.

Racemic dihydrothebainone (19), nordihydrocodeinone (21), and dihydrocodeinone (22) were synthesized in high overall yield from 3-methoxyphenethylamine (4), via the key intermediate (+/-)-1-bromonordihydrothebainone (18); the route utilized unprotected ph
