摘要：

Pudovik addition/[1,2]-phospha-Brook rearrangement asan efficienttool for generation of anionic nucleophiles is an attractive strategyfor the construction of C-C bonds in organic synthesis. Herein,we report organocatalytic 1,6-conjugate addition of para-quinone methides utilizing Pudovik addition/[1,2]-phospha-Brookrearrangement. Chiral guanidine-sulfonamide catalyzed the three-componentreaction efficiently, providing biologically active oxindole/biaryl/phosphorus-basedstructures in high yields with excellent diastereo- and enantioselectivities.A possible bifunctional catalytic mode was proposed to elucidate thechiral control of this process.
