The reaction of nitrones, derived from benzaldehydes having an olefinic dipolarophile at the o-position, with DMAD provides the first example for the inter- and intramolecular double 1,3-dipolar cycloaddition.

1,3-Dipolar systems derived from o-(2-furylmethyloxy)benzaldehyde undergo an intramolecularcycloaddition to the furan ring, giving the corresponding cycloadducts; this provides the first example for the intramolecular 1,3-dipolar cycloaddition to a furan ring.
