para-Substituted N-phenylpyrrolidines, -piperidines. -perhydroazepines and -morpholines react with oxalyl chloride and DABCO to give the pharmaceutically useful intermediates, N-ω-haloalkylisatins under mild conditions and generally good yields.
对位取代的 N-苯基吡咯烷,-哌啶。-全氢氮杂和-吗啉与草酰氯和 DABCO 反应生成可药用中间体 N-ω-卤代烷基靛红在温和条件下且通常收率良好。
