New methods for the synthesis of oxindole alkaloids. Total syntheses of isopteropodine and pteropodine
The 2-oxindole alkaloids isopteropodine (11) and pteropodine (12) were conveniently synthesised from the known pentacycle (9) via a new and general protocol for oxidation and rearrangement of carboline lactams into 3,3-disubstituted-2-oxindoles.
