Step AAE (1): Followed the method of B. Miller and H.-S. Wong Tetrahedron 1972, 28, 2369. Bromine (0.651 mL, 12.6 mmol) in was added dropwise to a solution of cyclohexane-1,2-dione (1.35 g, 12.0 mmol) in CCl4 (30 mL) at 0° C. The reaction mixture was allowed to warm to rt. The resulting solution was concentrated in vacuo to afford 3-bromocyclohexane-1,2-dione. The crude product, which is prone to decomposition, was used for subsequent chemistry without purification or characterization.
