A conceptually new and straightforward introduction of sulfonyl groups at the C-7 position of an indole ring has been achieved via AlCl(3) mediated unexpected regioselective sulfonyl group migration for N-alkyl/aryl/heteroarylsulfonyl indoles affording potential inhibitors of Mycobacterium tuberculosis H37Rv chorismate mutase.

AlCl3-mediated unexpected migration of sulfonyl groups allows for the synthesis of 7-sulfonyl indoles with potential as inhibitors of Mycobacterium tuberculosis H37Rv chorismate mutase.
