A simple and efficient FeCl3-promoted cyclization/chlorination of cyclic tosylamine-tethered 8-aryl-2-en-7-yn-1-ols was observed. The reaction proceeded instantaneously at 23 °C in air to afford (Z)-4- (arylchloromethylene)-substituted azaspiro
Trifluoromethanesulfonic acid-catalyzed tandem semi-pinacol rearrangement/alkyne-aldehyde metathesis reaction of arylpropagylsulfonamide- tethered 2,3-epoxycyclohexan-1-ols to spiropiperidines
