The spirooxindole scaffolds are the structural centerpieces of a large number of alkaloids and unnatural compounds which exhibit pronounced biological and medicinal activities.[1-3] In the past few years, a flourish of asymmetric reactions targeting the construction of highly strained chiral spirooxindole structures have been witnessed.[4] An efficient organocatalytic aza/oxa/thia-MichaelMichael cascade reaction for the asymmetric synthesis of highly functionalized spirooxindole tetrahydroquinolines, chromans and tetrahydrothiophenes scaffolds has been reported through a formal [4/3+2] annulation strategy.
