Article abstract of DOI:10.1016/S0040-4039(96)02105-3

The synthesis of diastereomeric 4,5-methano-L-proline 3-acetic acids is described starting from D-serine. The key reactions include a free-radical carbocyclization and an acid-catalyzed destannylative cyclopropanation of an iminium ion intermediate. Copyright (C) 1996 Elsevier Science Ltd.
