The tetracycline class of antibiotics has played a major role in the treatment of infectious diseases for the past 50 years. However, the increased use of the tetracyclines in human and veterinary medicine has led to resistance among many organisms previously susceptible to tetracycline antibiotics. The modular synthesis of tetracyclines and tetracycline analogs described provides an efficient and enantioselective route to a variety of tetracycline analogs and polycyclines previously inaccessible via earlier tetracycline syntheses and semi-synthetic methods. These analogs may be used as anti-microbial agents or anti-proliferative agents in the treatment of diseases of humans or other animals.

The present invention provides omadacycline crystalline freebase and methods of synthesis thereof. The present invention also provides pharmaceutical compositions comprising omadacycline crystalline freebase and methods of use thereof for treating bacterial infections. The present invention also provides methods of purifying crude omadacycline freebase that comprise crystallization to produce crystalline omadacycline freebase. The omadacycline crystalline freebase may also be used to prepare salts of omadacycline, e.g., a tosylate salt.
