摘要
A chiral N-heterocyclic carbene (NHC)-catalyzed formal [4+2] annulation of beta-methyl substituted enals with isatins was developed to construct six-membered spirolactones bearing highly congested quaternary carbon stereocentersin good yields and high enantioselectivities. The strategy realized a challenging remote gamma-carbon addition of enals and chiral control of beta-methyl substituted enals in the presence of the NHC catalyst only.
