1-Methyl-3, 4-benzo-7-thia-2-azabicyclo[3.3.1]nonane 7-oxide has been synthesized by the reaction of quinaldine with methylsulfinylmethyl carbanion, and its structure has been elucidated on the basis of spectral data and some chemical evidence. The conformation of the product has been further investigated by means of proton and carbon-13 nuclear magnetic resonance spectroscopy together with molecular mechanics calculations. The molecular mechanics calculations indicate that the stable conformer has a chair thiane ring with an equatorial sulfoxy group.

A simple, efficient, and ecofriendly procedure has been developed for the synthesis of quinoline and its derivatives in a one-pot reaction of aniline with crotonaldehyde or methyl vinyl ketone using phosphomolybdic acid as solid acid catalyst in miceller media. The catalyst was easily recycled and reused.
