A palladium‐catalyzed intramolecular α‐arylation and defluorinative aromatization strategy for the synthesis of polysubstituted 2‐naphthols is reported. With ortho‐bromobenzyl‐substituted α‐fluoroketones as the substrates and palladium acetate/triphenylphosphine as the catalyst, this method features good functional group tolerance, readily available catalyst and starting materials, and high yields
报道了钯催化的分子内α-芳基化和脱氟芳构化策略,用于合成多取代的2-萘酚。该方法以邻溴苄基取代的α-氟酮为底物,并以乙酸钯/三苯膦为催化剂,具有良好的官能团耐受性,易于获得的催化剂和起始原料以及高收率的特点。该策略的应用通过合成有用的结构单元(例如,石脑油[2,3- b ]呋喃,萘酚AS-D和配体/催化剂)得到证明。
