title: Highly enantioselective catalytic 1,3-dipolar cycloaddition involving 2,3-allenoate dipolarophiles.
abstract: A bisphosphoric acid-catalyzed 1,3-dipolar cycloaddition of buta-2,3-dienoates with azomethine ylides yields 3-methylenepyrrolidine derivatives with excellent enantioselectivity (up to 97% ee).
