参考标题:Synthesis Of 2-Substituted Benzo[B]Thiophenes Via Gold(I)-Nhc-Catalyzed Cyclization Of 2-Alkynyl Thioanisoles 作者:Christopher C. Dillon,Bagieng Keophimphone,Melissa Sanchez,Parveen Kaur,Hubert Muchalski 摘要:Developed For The Construction Of A Benzo[b]Thiophene Core Via Cyclization Reaction Of Alkynes. Although Few Catalytic Reactions Were Disclosed, Most Methods Rely On Stoichiometric Activation Of Alkynes. Here We Report An Efficient Method For The Synthesis Of 2-Substituted Benzo[b]Thiophenes From 2-Alkynyl Thioanisoles Catalyzed By A Gold(I)-Ipr Hydroxide That Is Applicable To A Wide Range Of Substrates
