3-Bromoindoles, 3-unsubstituted indoles, or 3-formylindoles on treatment with NBS (2,3, or 4 molar equivalents, respectively) in -butanol give 3,3-dibromooxindoles, and these readily yield the corresponding isatins on hydrolysis.
用NBS(分别为2,3或4摩尔当量)在-丁醇中的N-溴代吲哚,3-未取代的吲哚或3-甲酰基吲哚得到3,3-二溴代吲哚,它们在水解时容易产生相应的靛红。
