- In
organic chemistry, a
nitrone is a
functional group consisting of an N-oxide of an imine. The
general structure is R1R2C=N+(−O−)(−R3),
where R3 is not...
- The
nitrone-olefin (3+2)
cycloaddition reaction is the
combination of a
nitrone with an
alkene or
alkyne to
generate an
isoxazoline or
isoxazolidine via...

nitrone dipole, and
acyclic and
endocyclic nitrones are all tolerated. This
large allowance provides a lot of
flexibility for

cycloaddition reaction is a (2+3)cycloaddition. The
Nitrone-olefin

rearrangement has also been
successfully performed on
haloimines and
