"I" did it: An iodine(III)-mediated bromocarbocyclization was elaborated as an efficient tool for the synthesis of oxoindoles. This method is applicable to a variety of structurally different substrates, also with chemically sensitive groups, and gives access to the heterocycles in a regio- and stereoselective fashion (see scheme). The indole-2-ones obtained can be converted easily into structurally complex target compounds, such as the alkaloid physostigmine. Copyright
