A new strategy toward indole alkaloids involving an intramolecular cycloaddition/rearrangement cascade

Article abstract of DOI:10.1021/jo049808i

The intramolecular Diels-Alder reaction between an amidofuran moiety tethered onto an indole component was examined as a strategy for the synthesis of Aspidosperma alkaloids. Furanyl carbamate 23 was acylated using the mixed anhydride 26 to provide amidof
