资源简介：
The
enantioselective construction of five-membered spirocyclic
oxindoles via a double Michael cascade reaction is described by using
dipeptide-based multifunctional quaternary phosphonium salt catalysts.
The desired products were obtained in excellent yields (up to 94%)
and good to high stereoselectivities (up to >19:1 dr and 99% ee).
