title: Switching stereoselectivity in rhodium-catalysed 1,4-additions: The asymmetric synthesis of 2-substituted pyrrolizidinones.
abstract: The appropriate choice of organometallic nucleophile enables the straightforward preparation of different stereoisomers of 2-substituted pyrrolizidinones utilising the rhodium-catalysed 1,4-addition reaction.
