The iodocyclisation of a range N-allyl and N-homoallylguanidines using I2/K2CO3 has been found to lead to a series of novel heterocycles which undergo selective rearrangements on variation of the reaction conditions, and predictable protecting group migration in the presence of trifluoroacetic acid in methanol.
已经发现,使用I 2 / K 2 CO 3对一系列N-烯丙基和N-高烯丙基胍的碘环化可导致一系列新的杂环,这些杂环在反应条件变化时发生选择性重排,并且在存在下可预测的保护基团迁移三氟乙酸的甲醇溶液。
