biological activities in vitro both toward chloroquino‐resistant FcB1‐Columbia and FcM29‐Cameron strains and Nigerian chloroquino‐sensitive strain of Plasmodium falciparum. Cytotoxicity of the most active compounds was estimated showing that one compound (10) exhibited a selective activity against malaria parasite (selectivity indexes of 52 and 144). Antiplasmodial activity of this derivative was optimized
We report a metal-, acid-, and base-free 2-(bromomethyl)naphthalene (2-BMN)-promoted organocatalytic Cloke–Wilson rearrangement of chain doubly activated cyclopropanes for the construction of 2,3-dihydrofurans via a carbocation-initiated tandem intramolecular ring-opening/recyclization process. The strategy is especially suitable for the construction of furan units in complex molecules, providing a
Cycloheptenones are widespread in natural products and bioactive molecules. An efficient and convenient NaH-mediated CopeRearrangement of doubly activated vinylcyclopropanes is reported for the synthesis of cyclohepten-4-ones. These flexible intramolecular reactions were applicable to a wide range of substrates and could be performed on gram scale. The derivatization of the product leads to short
环庚烯酮广泛存在于天然产物和生物活性分子中。据报道,一种高效且方便的 NaH 介导的双活化乙烯基环丙烷 Cope 重排用于环庚烯-4-酮的合成。这些灵活的分子内反应适用于多种底物,并且可以在克规模上进行。产品的衍生化可以快速高效地合成一些有用的功能分子。
