Pd-catalyzed intramolecular cyclizations of oxime esters with 1,2-dialkylated alkenes provide an entry to dihydropyrroles. Substrate and catalyst controlled strategies for selective product formation are outlined.

In earlier work, we outlined further the scope of the oxime ester R-group for cyclizations of this type (ACIE, 2012, 1675); a wide range of alkyl- and aryl-substituents were tolerated. The present manuscript explores the scope of 1,2-disubstituted alkene acceptors.
