Abstract
In

Content
is
organized
by
several
main

for
‐azirines
such
as‐
Neber
rearrangement,
decomposition
vinyl
azides,
oxidative
cyclization
enamines,

compounds
nitriles,

Abstract
A
new
environmentally
friendly
and
efficient
strategy
for
preparing
trifluoromethylated
pyrrolidones
has
been
developed.
The
process
involves
using
visible
light
to
induce
radical
cyclization
of
1,5‐dienes
with
CF
3
SO
2
Na,
resulting
in
excellent
regioselectivity.
This
method
uses
less
expensive
easy‐to‐store
trifluoromethylation
reagents,
making
it
an
attractive
option.
Additionally,
the
can
be
easily
modified
preliminary
mechanistic
studies
have
presented.
