An efficient copper-free Pd(OAc)2/Ruphos-catalyzed Sonogashira coupling of 1-chloroisoquinolines in the formation of 1-alkynyl-3-substituted isoquinolines
摘要:
An efficient, copper-free Sonogashira coupling reaction of 1-chloroisoquinolines and terminal alkynes, catalyzed by Pd(OAc)(2)/Ruphos, in the presence of Et3N and tetrahydrofuran leads to the formation of 1-alkynyl-3-substituted isoquinolines in good yields.
