Described herein is a general and mild catalytic asymmetric 1,6-conjugate addition of para-quinone methides (p-QMs), a class of challenging reactions with previous limited success. Benefiting from chiral BrOnsted acid catalysis, which allows insitu formation of p-QMs, our reaction expands the scope to general p-QMs with various substitution patterns. It also enables efficient intermolecular formation of all-carbon quaternary stereocenters with high enantioselectivity.
