chloroallyllithium et le gem-chloro(méthyl)allyllithium réagissent facilement avec les esters aliphatiques et aromatiques: selon les conditions utilisées pour l'hydrolyse, la réaction peut conduire à des cétones α- ou γ-chlorées β-éthyléniques, aux cétones α- ou γ-chlorées α-éthyléniques isoméres et à des acyloǐnes α-éthyléniques.

reaction of 3-chloroallyltrimethylsilane (1) with acid chloride. The ketone was converted into αβ-unsaturated epoxide (3) regioselectively in good yield via reduction with NaBH4 or LiAlH4 followed by treatment with NaOH. Treatment with methyl lithium instead of reduction gave homologous epoxide (5).

1-aryl-2-chlorobut-2-en-1-ones. For the synthesis of these α-chloroenones, a two-step sequence was developed consisting of the allylation of the corresponding aldehyde with 3-dichloroprop-1-ene, followed by oxidation and further isomerization. The selective cooperative catalytic system involving ene-reductases (EREDs) and alcohol dehydrogenases (ADHs) afforded the desired opticallyactive chlorohydrins under mild
