(±)-Convolutamydine A (5) has been prepared by a concise synthesis form 3,5-dibromoaniline using a modified Sandmeyer methodology. The modified Sandmeyer methodology has also been found to be beneficial for the synthesis of other α-isonitrosoacetanilides. The 4,6-dibromohydrocyoxindole nucleus was further confirmed by comparison with the isomeric 5,7-dibromohydroxyoxindole.
