Stewart |发布日期:2020.5.1 摘要:A Rh(II)-Catalyzed Reaction Between 1-Tosyl-1,2,3-Triazoles And Halohydrins To Provide 2,6-Substituted 3,4-Dihydro-2H-1,4-Oxazines Under Basic Conditions. The Reaction Is Proposed To Undergo A Rhodium Carbenoid 1,3-Insertion Into O-H Followed By An Annulation. The Scope Includes Phenyl Or Alkenyl C4-Substituted Triazoles And A Range Of Halohydrins Using Catalytic Rh2Oct4 And K2Co3. A Synthesis Of The
