P -TsOH promoted synthesis of benzo-fused O-heterocycles from alkynols via ring contraction and C-O scission strategy

Article abstract of DOI:10.1039/c8gc00749g

Here, we report the first divergent synthesis of benzo-fused O-heterocycles by p-toluene sulfonic acid promoted cascade reactions involving alkyne hydration, double cyclization, ring contraction and C-O bond cleavage from alkynols. The reaction mechanism
