Novel Palladium-Catalyzed Acyloxylation/Cyclization of 2-(3′-Alkenyl)indoles
摘要:
A new and mild palladium(II)-catalyzed reaction for the intramolecular acyloxylation/cyclization of 2-(3'-alkenyl)indoles was developed. The newly formed cycles involve oxygen-containing functionalized groups, which might be transferred further to provide other indole derivatives.
The palladium-catalyzed borylative cyclization via C—H activation has been developed. By this chemistry, the indole-fused dihydro-pyrrole motif, which is a kind of important unit in natural products and bio-active molecules, could be constructed and installed with a boric ester group. Furthermore, the utilities of products have been illustrated by the study of further transformations. Importantly,
