A new and efficient strategy for the synthesis of substituted quinolines via electrophilic cyclization is developed. The intramolecular cyclization of 1-azido-2-(2-propynyl)benzene 1 proceeds smoothly in the presence of electrophilic reagents (I2, Br2, ICl, NBS, NIS, and HNTf2) in CH3NO2 at room temperature or in the presence of catalytic amounts of AuCl3/AgNTf2 in THF at 100 °C to afford the corresponding
开发了一种通过亲电环化合成取代喹啉的新的有效策略。在室温下,在CH 3 NO 2中存在亲电试剂(I 2,Br 2,ICl,NBS,NIS和HNTf 2)的情况下,1-叠氮基-2-(2-丙炔基)苯1的分子内环化过程顺利进行。或在100°C的THF中催化量的AuCl 3 / AgNTf 2的存在下,以高至高收率得到相应的喹啉2。对于亲电子试剂,根据试剂类型,E等于2可以是I,Br或H,而E等于2 在亲电催化剂的情况下,H为H。
