资源简介：
A new metal-free bicyclization reaction
of 1,7-enynes anchored
by α,β-conjugates with arylsulfonyl radicals generated
in situ from sulfonyl hydrazides has been established using tert-butyl hydroperoxide and tetrabutylammonium iodide.
The reactions occurred through sulfonylation/6-exo-dig/6-exo-trig bicyclization/in situ desulfonylation/5-exo-trig cyclization/alkyl or alkenyl migration cascade mechanism
to give benzo[j]phenanthridines regioselectively.
