Mr. Fielding et al., Novel synthesis of oxindoles from carbamoyl chlorides via palladium catalysed cyclisation-anion capture, CHEM COMMUN, (22), 2000, pp. 2239-2240
The synthesis of 3,3-disubstituted and 3-methyleneoxindoles by palladium(0)
catalysed cyclisation of carbamoyl chlorides onto proximate alkene or alky
ne groups has been achieved in good yields.
