The synthesis of carbon linked bis-benzylisoquinolines using Mizoroki–Heck and Sonagashira coupling reactions
摘要:
Novel laudanosine dimers in which two laudanosine units are linked at C-2' via a two or three-carbon linker (alkane, alkene or alkyne) have been prepared using palladium-catalysed cross-coupling reactions (Mizoroki-Heck and Sonagashira reactions). In one example, a second three-carbon linker between the two isoquinoline N-atoms was also present leading to a novel macrocyclic ring system. Crown Copyright (C) 2008 Published by Elsevier Ltd.
