  Microwave-Assisted One-Carbon Chain Extension in the Preparation of Terminal α-Hydroxy Ketones

  摘要：

  The microwave-assisted synthesis of terminal -hydroxy ketones from acid chlorides and tris(trimethylsiloxy)ethylene in the presence of triethylamine is reported. The use of triethylamine had several advantages in the reaction: it increased the reactivity of the acid chloride, acted as a scavenger of the HCl that was produced in the reaction, protected the silylated enol from decomposition, and made the excess use of the silyl reagent unnecessary. Mechanistic effects of triethylamine are discussed. Effects of various base additives, reaction temperatures, reaction times, and solvents in the reaction are compared.
