Abstract
This work describes a general protocol for the oxidation of indole and oxindole derivatives with dimethyldioxirane to give 3-hydroxyoxindoles present in many naturalproducts. This strategy allowed us to synthesize the naturalproduct1, to carry out the first total synthesis of 4, a formal total synthesis of donaxaridine (5) and to achieve the synthesis of pyrroloindoline 8, a debromo analogue of the naturalproduct flustraminol B (7).
