BROMODECARBONYLATION AND BROMODECARBOXYLATION OF ELECTRON-RICH BENZALDEHYDES AND BENZOIC ACIDS WITH OXONE® AND SODIUM BROMIDE
摘要:
Benzaldehydes and benzoic acids bearing ortho- and para-electron donating substituents having unshared electron-pair have undergone bromodecarbonylation or bromodecarboxylation on treatment with sodium bromide in the presence of Oxone(R) in aqueous methanol.

electrochemical transformation and the high reactivity of chlorine. By utilizing Cl3CCN as the chloride source, donating up to all three chloride atom, the reaction could generate and consume the chlorine in situ on demand to achieve the chlorination of aromaticcompounds and electrodeficient alkenes.
Halogenated derivatives of two synthetic anti-tuberculosis agents, thioacetazone and p-aminosalicylic acid, have been synthesized. In general, the halogenated compound has the structure of Structure I:
wherein X1 is a halogen and X2 is a second halogen or hydrogen, and Y is sulfur or oxygen; or, has the structure of Structure IV:
wherein X1 is a halogen and X2 is a second halogen or hydrogen. Alternatively, the halogenated compounds may be pharmaceutically acceptable salts of these compounds. These halogenated derivatives possess anti-mycobacterial activity and are particularly useful for the treatment of Mycobacterium tuberculosis infections. In particular, fluorinated analogs of thioacetazone and p-amino-salicylic acid have been synthesized for use as anti-tuberculosis therapeutic agents either alone or in combination with other conventional anti-tuberculosis therapeutic agents.
