Efficient organocatalysis of the intramolecular Michael reaction of formyl enones, such as 1 , by an imidazolidinone catalyst leads to the corresponding ketoaldehydes in excellent yields and with high enantioselectivities (see scheme). This reaction can be included as part of a tandem process, as the ketoaldehyde products undergo aldolization readily to give hydrindenones, such as 2 . Bn=benzyl, Ms=methanesulfonyl.
