Flexible Synthesis of Planar Chiral Azoninones and Optically Active Indolizidinones

2014

The flexible synthesis of defined substituted optically active indolizidinones starting from chiral pool (S)-proline and trans 4-hydroxy-(S)-proline is described. Several defined 2-vinylpyrrolidines were generated in short sequences. The aza-Claisen rearrangement using chloro and phenylketene equivalents delivered nine-membered-ring lactams with up to three stereogenic centres and pS-arranged E olefins. Depending on the substitution pattern, certain azoninones had a flexible conformation and showed pS/pR double-bond flipping. Treatment of the unsaturated lactams with the soft electrophile iodine induced diastereoselective transannular ring contractions. Here, the planar chiral arrangement o…
