The resorcylicacidlactones (RAL) are endowed with diverse biological activity ranging from transcription factor modulators (zearalenone and zearalenol) to HSP90 inhibitors (radicicol and pochonin D) and reversible (aigialomycin D) as well as irreversible kinase inhibitors (hypothemycin and other RAL containing a cis‐enone). Our interest in broadening the diversity of this family beyond naturally
A nucleophilic chiral amidophosphate-halo-Lewis acid cooperative catalysis has been developed for the site-, diastereo-, and enantioselective iodocyclization of 2-geranylarenols with molecular iodine to give the corresponding iodo-containing polycyclic compounds with good levels of selectivity. The sterically demanding 3,3′-substituents of the chiral amidophosphate derived from (R)-BINOL are critical
已开发出一种亲核手性氨基磷酸酯-卤素-路易斯酸协同催化,用于 2-香叶基芳酚与分子碘的位点选择性、非对映选择性和对映选择性碘环化,以生成具有良好选择性的相应含碘多环化合物。衍生自 ( R )-BINOL的手性氨基磷酸酯的空间要求高的 3,3'-取代基对于在 2-香叶基芳醇的受阻较小的末端烯基部分诱导位点选择性碘化至关重要。
