Abstract
Spiroindoline lactams 9 and imides 11 were efficiently and diastereose lectively prepared by photocyclization of N-arylenaminolactams 8 and e sters 5 respectively. Imides 11 were conveniently transformed into the known indolines 13 and 14 which are key intermediates for the synthes is of (+/-)-vindorosine and Aspidosperma alkaloids.
