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; R1 through R11 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 R11, 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.
