Pictet–Spengler/Palladium Catalyzed Allenylation and Carbonylation Processes
摘要:
The tactical combination of the Pictet-Spengler reaction with Pd catalyzed reactions with allene and with carbon monoxide provides rapid access to a range of tetrahydro-beta-carboline and tetrahydroisoquinoline derivatives via intramolecular trapping of intermediate pi-allyl- and acyl-palladium(II) complexes by the indolic or secondary amino moieties generating fused azepine and delta-lactam derivatives. Chiral tryptophan examples are also described. (C) 2000 Elsevier Science Ltd. All rights reserved.
