towards their synthesis, notably from seco-acids, a macrolactonization promoter system that is effective, selective, flexible, readily available, and, insofar as possible, compatible with manifold functional groups is still lacking. Herein, we describe a strategy that relies on the formation of a mixed anhydride incorporating a pentafluorophenyl group which, due to its high electronic activation enables
大环内酯是一类特殊的天然和合成产品,在精细化学品和制药行业有着广泛的应用。尽管在合成方面取得了所有进展,特别是从seco-酸,一种有效的、选择性的、灵活的、容易获得的并且尽可能与多种官能团相容的大环内酯化促进剂系统仍然缺乏。在这里,我们描述了一种策略,该策略依赖于形成包含五氟苯基的混合酸酐,由于其高电子活化,可以方便地获得具有广泛多功能性的大环内酯、大二内酯和酯。进行动力学研究和 DFT 计算以合理化五氟苯基在大环内酯化反应中的反应性。
