ABSTRACT Molecular iodine has been used for the regioselective, one pot, direct synthesis of 3-iodoflavones from 2′-allyloxy chalcones, 2′-hydroxy chalcones and flavones. Allyl deprotection, cyclization dehydrogenation and α-iodination of 2′-allyloxychalcones has been achieved in a single step to offer 3-iodoflavones. GRAPHICAL ABSTRACT
摘要 分子碘已被用于区域选择性、一锅法、直接从 2'-烯丙氧基查耳酮、2'-羟基查耳酮和黄酮合成 3-碘黄酮。2'-烯丙氧基查耳酮的烯丙基脱保护、环化脱氢和 α-碘化已在一步中实现,以提供 3-碘黄酮。图形概要
