2-dihydronaphthalene derivatives are accessed via two complementary synthetic strategies. The careful optimization of the reaction conditions required for the elimination step in one route has allowed both the identification of an anchimerically assisted reaction pathway and, more importantly, access to a divergent reaction pathway toward fluorinated 1,3-amino alcohols from a common intermediate just by adjusting
富含对映体的1-氨基-4-氟-1,2-二氢萘衍生物可通过两种互补的合成策略获得。在一条途径中对消除步骤所需的反应条件进行了仔细的优化,不仅可以鉴定出一种由邻氨基苯甲酸辅助的反应途径,而且更重要的是,可以从一种常见的中间体中直接获得一条通往氟化1,3-氨基醇的歧化反应途径。通过调整使用的碱的当量数。
