Title: Heck arylation of N-Boc-3-pyrrolines and N-Boc-2-pyrrolines with diazonium salts; Efficient syntheses of five-membered 4-aryl endocyclic enecarbamates and N-Boc-2,4-diaryl 3-pyrrolines

Abstract: Practical and efficient Heck arylations of N-Boc-3-pyrrolines and N-Boc-4-aryl-2-pyrrolines (endocyclic enecarbamates) with several arenediazonium tetrafluoroborate salts were accomplished. This methodology permitted the preparation of a series of 4-aryl endocyclic enecarbamates which were used in a subsequent Heck arylation to produce biaryl-3-pyrrolines in good yields without the need for phosphine ligands, excess of olefin, and stringent reaction conditions.
