Synthesis of polycyclic lactams via intramolecular dipolar cycloadditions of stabilized azomethine ylides
Martin,Cheavens
, p. 7017 - 7020 (1989)
A stereoselective two step sequence for the construction of fused pyrrolidone ring systems has been developed which features the intramolecular [3 + 2] dipolar cycloaddition of unsaturated azomethine ylides. The ylides are produced upon reaction of aminomethylphosphonates with α,ω-olefinic aldehydes, followed by oxidative removal of the phosphonate ester group using a newly developed method.

The Pd-catalyzed migratory cycloisomerization of N-allyl-o-allenyl aniline derivatives is first reported to give indoles having a substituent at the 2-position.
