report
a
novel
strategy
for
the
regioselective
synthesis
of
aromatic
and
heteroaromatic
2,3-dihydrooxazoles
from
2-alkynyl-1,3-dithianes
nitrones.
This
method
exploits
1,3-dithiane
umpolung,
nucleophilic
cycloaddition,
rearrangement
processes
to
achieve
rapid
assembly
dihydrooxazole
molecules.
The
is
extremely
mild,
achieving
complete
conversion
within
one
min
under
air
at
25
°C
with
high
efficiency.
