nortropane analogues closely related with Calystegines have been prepared in excellent chemical yields and complete selectivity. A synthetic strategy based on consecutive nucleophilic allylation, oxidation, and intramolecular dipolar cycloaddition was developed. The formation of key intermediate cycloadducts were observed to take place through the recently confirmed thermally induceded 2-aza-Cope rearrangement
已经以优异的
化学产率和完全的选择性制备了两种与Calystegines密切相关的新的多羟基化的正烷烷类似物。建立了基于连续亲核烯丙基化,氧化和分子内偶极环加成反应的合成策略。观察到关键中间体环加合物的形成是通过最近确认的热诱导的硝酮的2-氮杂-Cope重排而发生的。
