Synthesis of alkynyl(phenyl)iodonium triflates and their reaction with diethyl 2-aminomalonate
摘要:
Alkynyl(phenyl)iodonium triflates 9 react with the Li (or K) salt of diethyl 2-[(diphenylmethylene)amino]malonate (10) (M = Li or K) to give the corresponding diethyl 2-alkynyl-2-[(diphenylmethylene)amino]malonate (11) in 30-95% yield.
