A new efficient route to (±)-physostigmine and (±)-physovenine by means of 5-exo selective aryl radical cyclization of o-bromo-N- acryloylanilides

Bu3SnH-mediated aryl radical cyclization of o-bromo-N-acryloylanilides 16 and 17 proceeded in a 5-exo manner exclusively to give, in high yields, oxindoles 3 and 4, the key intermediates for the synthesis of (±)- physostigmine and (±)-physoveni
