Nonsymmetric
diarylethenes
with
an
additional
"stiff"
cyclohexenol
ring
undergo
various
types
of
tandem
transformations
launched
by
light-induced
6π-photocyclization.
Among
these,
there
are
two

reactions
(formal

The
Mallory
reaction,
which
involves
the
photocyclization
of
stilbenes/diarylethenes
and
their
analogues
into
polycyclic
aromatics,
is
significant
synthetic
importance.
However,
its
application
to
tertiary
benzanilides
has
not
been
explored

Besides,
most
reported
reactions
require
ultraviolet
irradiation.
In
this
study,
we
show
first
reaction
promoted
by
visible
