Chiral
phosphoric
acid
based
organocatalysis
and
visible-light
photocatalysis
have
both
emerged
as
promising
technologies
for
the
sustainable
production
of
fine
chemicals.
In
this
context,
we
envisioned
design
synthesis
a
new
class
chimeric
catalytic
entities
that
would
feature
capabilities.
Given
their
multitask
nature,
such
catalysts
be
particularly
attractive
development
transformations,
tandem
processes
in
particular.
Toward
goal,
several
BINOL-based
chiral
backbones
presenting

or
two

prepared

The
utility
these
photoactive
organocatalysts
is

demonstrated
enantioselective

Of
note,
C1-symmetric
organo/photocatalyst
has
shown
better
activity
than

Visible
light
organophotoredox
catalysis
has
emerged
as
an
invaluable
tool
for
organic
synthetic
transformations
since
it
works
brilliantly
in
tandem
with
substrates
and
been
known
to
create
unique
chemical
environment
transformations.
Dicyanopyrazine
(DPZ),

catalyst,

potential
through
its

synthesis
necessitates
attention
of
