参考标题:Metal-Free Synthesis Of 2-N,N-Dialkylaminobenzoxazoles Using Tertiary Amines As The Nitrogen Source 作者:Mookda Pattarawarapan,Dolnapa Yamano,Nitaya Wiriya,Wong Phakhodee |发布日期:2019.5.17 摘要:The Unprecedented Reaction Of Tertiary Amines With 2(3H)-Benzoxazolones Has Been Investigated. In The Presence Of The Ph3P-I2 Reagent System, The Reaction Of Both Acyclic And Cyclic Aliphatic Tertiary Amines Led To The Formation Of 2-N,N-Dialkylaminobenzoxazoles With The Selective Cleavage Of An Alkyl Group. Especially, N-(2-Iodoethyl)Piperazinyl Derivatives Were Rapidly Produced In Good Yields When
