Key features of the β-isocupreidine (β-ICD)-catalyzed asymmetric Baylis-Hillman reaction of aldehydes with 1,1,1,3,3,3-hexafluoroisopropyl acrylate (HFIPA) are presented. In addition, an improved method using azeotropically dried β-ICD is described.

(Chemical Equation Presented) Going back to nature: Electron-deficient oxadienes and electron-poor acetylene carboxylates react in the presence of an organocatalyst to give natural product inspired tricyclic benzopyrones efficiently (up to 99% yield) and
