AlCl3 Mediated Unexpected Migration of Sulfonyl Groups: Regioselective Synthesis of 7‐Sulfonyl Indoles of Potential Pharmacological Interest.
ChemInform, 2013Co-Authors: Bagineni Prasad, Raju Adepu, Sandhya Sandra, C. Malla Reddy, Girdhar Singh Deora, D. Rambabu, G. Rama Krishna, Parimal MisraAbstract:The acetylation of indole (IIIe) in the presence of AlCl3 leads to desired 3-acetyl derivative (VII), whilst the analogous reaction of 2-tert-butylindoles (IIIa)—(IIId) is accompanied by an unexpected migration of the Sulfonyl group.

AlCl3 mediated unexpected migration of Sulfonyl Groups: regioselective synthesis of 7-Sulfonyl indoles of potential pharmacological interest
Chemical Communications, 2012Co-Authors: Bagineni Prasad, Raju Adepu, Sandhya Sandra, C. Malla Reddy, Girdhar Singh Deora, D. Rambabu, G. Rama Krishna, Parimal MisraAbstract:A conceptually new and straightforward introduction of Sulfonyl Groups at the C-7 position of an indole ring has been achieved via AlCl3 mediated unexpected regioselective Sulfonyl group migration for N-alkyl/aryl/heteroarylSulfonyl indoles affording potential inhibitors of Mycobacterium tuberculosis H37Rv chorismate mutase.

Selective Synthesis of 4-(Sulfonyl)-methyl-1H-pyrazoles and (E)-4,5-Dihydro-1H-pyrazoles from N-Allenic Sulfonylhydrazones.
ChemInform, 2014Co-Authors: Jun‐jie Hong, Yun-bin Zhou, Yu-wei Xiao, Zhuang-ping ZhanAbstract:A key feature of the title reaction is that the migration of the Sulfonyl Groups to different positions can be controlled by changing the Lewis acids.

Organic and Biomolecular Chemistry, 2014Co-Authors: Jun‐jie Hong, Yun-bin Zhou, Yu-wei Xiao, Zhuang-ping ZhanAbstract:Selective synthesis of 4-(Sulfonyl)-methyl-1H-pyrazoles and (E)-4,5-dihydro-1H-pyrazoles from N-allenic Sulfonylhydrazones with Sulfonyl group migrations has been developed. A key feature of these reactions is that the migrations of the Sulfonyl Groups to different positions can be controlled by changing the Lewis acids.

Sulfur-Based Protecting Groups for Pyrroles and the Facile Deprotection of 2-(2,4-Dinitrobenzene)sulfinyl and Sulfonyl Pyrroles
Journal of Organic Chemistry, 2005Co-Authors: Alison Thompson, R. Jonathan Butler, Meaghan N. Grundy, Andrea B. E. Laltoo, Katherine N. Robertson, T. Stanley CameronAbstract:The effectiveness of simple sulfinyl and Sulfonyl Groups as electron-withdrawing protecting Groups for pyrroles has been analyzed using 13C NMR spectroscopy and confirmed by consideration of X-ray crystal structures. Additionally, the 2,4-dinitrobenzenesulfinyl and Sulfonyl Groups are shown to be effective electron-withdrawing protecting Groups for pyrroles, and they can be removed by treatment with benzene thiol or thiolate under mild and specific conditions.
