Diisoindolothieno[2,4]diazepines via a diastereoselective N-acyliminium ion cyclization
摘要:
A high syn stereoselectivity, of the addition of an aromatic to the cyclic N-acyliminium ions generated from hydroxylactams 3a,b,e,f leading to the thieno[2,4]diazepines 4a,b,e,f is described. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
