Intramolecular amination of organoboronates occurs with a 1,2-metalate shift of an aminoboron ate complex to form azetidines, pyrrolidines, and piperidines. Bis(boronates) undergo site-selective amination to form boronate-containing azacycles. Enantiomerically enriched azacycles are formed with high stereospecificity.
The Titanium-Mediated Double Reductive Cleavage of Cyclic Sulfonamides for the Synthesis of Aryl Pyrrolidines
Khalifa, Aisha,Evans, Paul
, p. 2969 - 2975 (2019/02/26)
Reduction of a range of benzo-fused cyclic sulfonamides has been accomplished using low-valent titanium. This operationally simple method generates the corresponding aryl-substituted cyclic amines, typically, with good conversion. Notably, unlike our previous Li-NH3-based method, loss of heteroatom-based substituents (X) on the aromatic ring does not readily occur, and the robustness of this method was demonstrated with a synthesis of the Sceletium alkaloid mesembrane.

Inorganic pyrophosphatases are potential targets for the development of novel antibacterial agents. A pyrophosphatase-coupled high-throughput screening assay intended to detect o-succinyl benzoic acid coenzyme A (OSB CoA) synthetase inhibitors led to the unexpected discovery of a new series of novel inorganic pyrophosphatase inhibitors. Lead optimization studies resulted in a series of 3-(3-aryl-pyrrolidin-1-yl)-5-aryl-1,2,4-triazine derivatives that were prepared by an efficient synthetic pathway. One of the tetracyclic triazine analogues 22h displayed promising antibiotic activity against a wide variety of drug-resistant Staphylococcus aureus strains, as well as activity versus Mycobacterium tuberculosis and Bacillus anthracis, at a concentration that was not cytotoxic to mammalian cells.
Diastereoselective functionalisation of benzoannulated bicyclic sultams: Application for the synthesis of cis-2,4-diarylpyrrolidines

Double reduction of cyclic aromatic sulfonamides: A novel method for the synthesis of 2- and 3-aryl-substituted cyclic amines
Evans, Paul,McCabe, Thomas,Morgan, Ben S.,Reau, Sophie
, p. 43 - 46 (2007/10/03)
(Chemical Equation Presented) The facile double reduction of bicyclic aromatic sulfonamides was used to synthesize a variety of 2- and 3-aryl-substituted pyrrolidines and 2-phenylpiperidine. The method features a combined nitrogen protection and a traceless tether for the transposition of the aromatic moiety from nitrogen to carbon.

N-Substituted-3-arylpyrrolidines: Potent and Selective Ligands at Serotonin 1A Receptor
Ahn, Kyo Han,Lee, Seok Jong,Lee, Chang-Ho,Hong, Chang Y.,Park, Tae Kyo
, p. 1379 - 1384 (2007/10/03)
3-Arylpyrrolidines are synthesized through the coupling of N-benzyl-3-(methanesulfonyloxy)pyrrolidine with diarylcuprates. Pharmacological evaluation of a series of N-substituted-3-arylpyrrolidines toward several neurotransmitter receptors indicated that some of them are good ligands for serotonin 1A receptor. Particularly, N-pyrrolidines were found to be potent and selective ligands. A preliminary biological evaluation for several selected compounds indicated that they are potentially effective antianxiety and antidepressant agents.
Regioselective synthesis of 3-aryl substituted pyrrolidines via palladium catalyzed arylation: Pharmacological evaluation for central dopaminergic and serotonergic activity

, p. 241 - 246 (2007/10/03)
A series of 3-arylpyrrolidines has been synthesised via palladium catalyzed arylation and evaluated for dopaminergic and serotonergic activity in vitro and in vivo. Compounds substituted by electron withdrawing groups on the meta position of the aromatic ring, were found to be preferential dopamine autoreceptor antagonists.
