Transition-metal-free synthesis of 3-(1-pyrrolidinyl)quinolines and 3-(1-pyrrolidinyl)quinoline 1-oxides via a one-pot reaction of 3-(1-pyrrolidinyl)crotonates with nitrobenzenes

, p. 2397 - 2402 (2017/03/20)
A carbanion of tert-butyl 3-(1-pyrrolidinyl)crotonate adds to nitrobenzenes to form σH-adducts, which in the presence of pivaloyl chloride and triethylamine are converted into 3-(1-pyrrolidinyl)quinolines or 3-(1-pyrrolidinyl)quinoline 1-oxides depending on the nitrobenzene structure. This is the first methodology in which a quinoline ring is constructed from a substrate bearing a pyrrolidinyl ring. Starting from optically pure enamines, the method allows synthesis of the corresponding chiral products without racemisation.

A diastereoselective synthesis of (S)-3-(3-(3,5-dimethyl-1H-pyrazol-1-yl)phenyl)-4-((R)-3-(2-(5,6,7,8-tetrahydro-1,8-naphthyridin-2-yl)ethyl)pyrrolidin-1-yl)butanoic acid (1), a potential therapeutic agent for the treatment of Idiopathic Pulmonary Fibrosis, which is currently undergoing Phase I clinical trials is reported. The key steps in the synthesis involved alkylation of 2-methylnaphthyridine with (R)-N-Boc-3-(iodomethyl)-pyrrolidine, and an asymmetric Rh-catalysed addition of an arylboronic acid to a 4-(N-pyrrolidinyl)crotonate ester. The overall yield of the seven linear step synthesis was 8% and the product was obtained in >99.5% ee proceeding with 80% de. The absolute configuration of 1 was established by an alternative asymmetric synthesis involving alkylation of an arylacetic acid using Evans oxazolidinone chemistry, acylation using the resulting 2-arylsuccinic acid, and reduction. The absolute configuration of the benzylic asymmetric centre was established as (S).

scheme or table, p. 2829 - 2834 (2010/03/03)
Single enantiomer [(aryloxy)(pyridinyl)methyl]piperidine and pyrrolidine derivatives 5-9 are inhibitors of monoamine reuptake. Structure-activity relationships established that monoamine reuptake inhibition are functions of amine, pyridine isomer, aryloxy ring substitution and stereochemistry. Consequently, selective NRIs, selective SRIs, dual SNRIs and triple SNDRIs were all identified. Dual SNRIs 5l-a and 9c were evaluated in additional pharmacology and pharmacokinetic studies as representative examples from this series.
