摘要：A Sc(OTf)3-catalyzed dearomative [3 + 2] cycloadditionof benzazoles with donor–acceptor oxiranes through chemolectiveC–C bond cleavage of oxiranes山楂陈皮茶
was developed under mild conditions.This reaction provides an efficient method to construct benzazolo[3,2-]o xazole compounds in good yields and with high diastereolectivity.The reaction has
雅思4分a general substrate scope, and the donor–acceptoroxiranes with electron-donating and electron-withdrawing groups onthe aromatic ring afforded the desired cycloadducts.
