di-pimethane rearrangement
noun
A
photochemical
reaction
of
a
molecular
entity
comprising
two
p-systems,
separated
by
a
saturated
carbon
atom
(a
1,4-diene
or
an
allyl-substituted
aromatic
analog),
to
form
an
ene-
(or
aryl-)
substituted
cyclopropane.
The
rearrangement
formally
amounts
to
a
1,2
shift
of
one
ene
group
(in
the
diene)
or
the
aryl
group
(in
the
allyl-aromatic
analog)
and
‘bond
formation’
between
the
lateral
carbons
of
the
non-migrating
moiety.

正解を見る
A photochemical reaction of a molecular entity comprising two p-systems, separated by a saturated carbon atom (a 1,4-diene or an allyl-substituted aromatic analog), to form an ene- (or aryl-) substituted cyclopropane. The rearrangement formally amounts to a 1,2 shift of one ene group (in the diene) or the aryl group (in the allyl-aromatic analog) and ‘bond formation’ between the lateral carbons of the non-migrating moiety.
The di-pimethane rearrangement is a key step in the synthesis of complex organic molecules.
