It all adds up! A modified Feist–Bénary reaction employing a dominoMichael–alkylation sequence was designed for the enantioselective synthesis of 3(2 H)‐furanones. L‐Threonine‐derived tertiary amine/thiourea catalysts were prepared for the first time; such catalysts promoted the designed dominoMichael–alkylationreactions in a highly enantioselective manner (see scheme).

[GRAPHICS]We have found a new synthetic method for the preparation of the alpha-bromoketones that are brominated in the less activated terminal position of unsymmetrical ketones. Brominations in short reaction times (kinetically controlled) provided internally brominated compounds as a major product. However, brominations in longer reaction times (thermodynamically controlled) gave more of the terminally brominated compound through the reversible reaction by Br-2 and produced hydrogen bromide. Several brominated compounds at the terminal position were successfully prepared through the new synthetic route.
