Asymmetric Michael Addition

Regio- and enantio-selective Michael addition between azlactones with o-hydroxy chalcone derivatives is reported. Optically active N,O-aminals are obtained in good yields with good to excellent diastereo- and enantio-selectivities.

High Yields

A convergent and efficient NHC-catalyzed enantioselective tandem Michael addition/lactonization sequence of ynals with 1,2-dione is disclosed. This strategy expeditiously assembles the valuable optically active fused dihydropyranones in good to high yields and with excellent enantioselectivities.
