An asymmetric substrate-controlled Morita–Baylis–Hillman reaction as approach for the synthesis of pyrrolizidinones and pyrrolizidines
We describe herein an approach to the total synthesis of functionalized pyrrolizidinones and
pyrrolizidines. The synthetic sequence is based on a highly stereoselective substrate …

The crystal structure of the title compound, C14H14N2O5, contains two distinct conformers
in the asymmetric unit. The compound has three defined stereocenters, two of them …
