Synthesis of 6-bromo-2-arylindoles using 2-iodobenzoic acid as precursor
摘要:
The synthesis of 6-bromo-2-arylindoles starting from readily available 2-iodobenzoic acid is presented. Regioselective bromination of the latter was followed by Curtius rearrangement and trapping of the isocyanate with benzyl alcohol led to the benzyl carbamate of 2-iodo-5-bromoaniline. Chemoselective Sonogashira coupling of this compound with arylacetylenes followed by TBAF induced 5-endo-dig cyclization gave the desired bromo indoles. The method allows selective introduction of a bromine atom at the indole C-6 position. (C) 2011 Elsevier Ltd. All rights reserved.

The present invention is directed to small molecule inhibitors of the IgE response to allergens, which are useful in the treatment of allergy and/or asthma or any diseases where IgE is pathogenic. This invention also relates to phenyl-indole molecules that are cellular proliferation inhibitors and thus are useful as anticancer agents. This invention further relates to small molecules which suppress cytokines and leukocytes.
