The enantioselective synthesis of α-disubstituted N-heterocyclic carbonyl compounds has been accomplished using palladium-catalyzed allylic alkylation. These catalytic conditions enable access to various heterocycles, such as morpholinone, thiomorpholinone, oxazolidin-4-one, 1,2-oxazepan-3-one, 1,3-oxazinan-4-one, and structurally related lactams, all bearing fully substituted α-positions. Broad functional group tolerance was explored at the α-position in the morpholinone series. We demonstrate the utility of this method by performing various transformations on our useful products to readily access a number of enantioenriched compounds.

A compound useful as a building block for the manufacture of various compounds is represented by Formula A or D. In Formula A and D, z is 0 or 1; Q is a heteroatom; Rl through R1 1 and Ra through Rf are each independently hydrogen, a substituted or unsubstituted hydrocarbyl group, a substituted or unsubstituted heteroatom containing hydrocarbyl group, or a functional group; d, e and f are each independently 0 or greater; each of A, B and D is independently a carbon atom or a heteroatom; and two or more of R1 though R1 1, Ra through Rf and Y optionally combine to form a ring. In some embodiments, R8 and R9 combine to form a carbonyl group. In some embodiments, R2 and Y combine to form a ring with the Q atom. In some embodiments, the ring includes at least one double bond.
