Abstract
Catalytic diazosulfonylation of enynals with arylsulfonyl hydrazides has
been established by using tert-butyl hydroperoxide (TBHP) as the oxidant
with tetrabutylammonium iodide (TBAI) under a convenient system. The
reaction occurred through oxidative radical triggered S-exo-trig
carbocyclization cascading to afford sulfonylated diazoindenes
regioselectively. The new diazosulfonylation reaction features a broad
substrate scope, readily accessible starting materials, and a simple
one-pot process.
