资源简介：
Highly enantioselective (formal) hetero-Diels–Alder reactions
between chalcones and formylcyclopropanes are disclosed. The challenging
N-heterocyclic carbene (NHC)-bounded enolate intermediates from formylcyclopropanes
were captured for new C–C bond forming reactions. The reaction
products were obtained with high diastereo- and enantioselectivities
and could be easily transformed to optically pure multisubstituted
cyclohexane derivatives.
