Abstract
A metal-free remote oxytosylation of 8-amidoquinolines has been achieved using Koser’s reagent to produce 5-tosyloxy-8-amidoquinolines in good yields. This method is compatible with various functional groups present on the aromatic ring.
Key words
Koser’s reagent - C–H activation - 8-amidoquinolines - oxytosylation - hypervalent iodine reagentsSupporting Information
