A Facile Stereospecific Synthesis of 1, 3-Enynylsulfides via Sonogashira Coupling of (E)-α-Iodovinyl Sulfides with 1-Alkynes
摘要:
(E)-α-Iodovinyl sulfides 1 underwent the Sonogashira coupling reactions with terminal alkynes 2 in piperidine at room temperature in the presence of 5 mol% of Pd(PPh3)4 and 10 mol% of CuI to afford the corresponding 1, 3-enynylsulfides 3 stereospecifically in high yields.
