摘要
The first synthesis of the N'-tosylimine of N-glyoxyloyl-(2R)-bornane-10,2-sultam using a modified Holmes method is described. The N'-tosylimine was used as a dienophile in the Lewis acid-catalyzed diastereoselective imino-Diels-Alder reaction with cyclopentadiene to give cycloadducts with good diastereoisomeric excess. The direction of the asymmetric induction depends on the Lewis acid used. (C) 1997 Elsevier Science Ltd.
