Abstract
The carbonyl-olefin metathesis (COM) reaction is an attractive approach for the formation of a new carbon-carbon double bond from a carbonyl precursor. In principle, this reaction can be promoted by the activation of the carbonyl group with a Brønsted acid catalyst; however, it is often complicated as a result of unwanted side reactions under acidic conditions. Thus, there have been only a very few examples of Brønsted-acid-catalyzed COM reactions, all of which required specially designed setups. Herein, we report a new practical homogeneous Brønsted-acid-catalyzed protocol using nitromethane, a readily available solvent, to promote intramolecular ring-closing COM reactions.

Abstract
Various functionalised 4-amino-2-(methylthio)quinolines are synthesised through triflic acid-mediated N-heteroannulation of α-functionalized-β-anilino-β-(methylthio)acrylonitriles for the first time. The N-heteroannulation process is highly chemoselective and has mild reaction conditions. However, this process fails in the absence of the β-methylthio group in the acrylonitriles. In addition, a new double N-heteroannulation process is demonstrated to synthesise indolo[3,2-c]quinolines from non-heterocyclic precursors. Natural product isocryptolepine is synthesised in four steps from an acyclic precursor.

Abstract
Ciprofloxacin is a broad-spectrum antibiotic that is recognized as one of the World Health Organization's Essential Medicines. It is particularly effective in the treatment of Gram-negative bacterial infections associated with urinary, respiratory, and gastrointestinal tract infections. A streamlined and high yielding continuous synthesis of ciprofloxacin has been developed, which employs a chemoselective C-acylation step that precludes the need for intermediate isolations, extractions, or purifications. The end-to-end process has a residence time of 4.7 min with a 15.8 g/h throughput at laboratory scale and an overall isolated yield of 83%.
