  A Novel Darzens type reaction promoted by tributylstannylcarbamate

  摘要：

  Stannylcarbamate 1 proved to be a selective agent for generating organotin(IV) enolates from alpha-halo ketones. Thus, a Darzens reaction was achieved under mild and neutral conditions. The reaction took place without any side reactions and even with aliphatic alpha-halo ketones bearing enolizable alpha'-hydrogens. Various types of alpha,beta-epoxy ketones and esters were obtained in this one-pot reaction. The stereoselectivity of the reaction was influenced by changing the halogen substituent of the alpha-halo ketones and by additives. Moreover, the present method could be applied to gamma- and delta-halo ketones as enolate precursors, and five- and six-membered cyclic compounds were obtained.

  In the presence of Lewis acid TMSOTf, ring-opening reaction of aryl cyclopropyl ketone with arylaldehyde took place under mild conditions to give 2-(2-hydroxyethyl)-1,3-diarylpropenone in good yield. By protection of hydroxy group with triethylsilyl group (TES), the corresponding ring-opened product 7 was obtained in high yield with good geometrical selectivity.

  在路易斯酸TMSOTf的存在下，芳基环丙基酮与芳基醛的开环反应在温和的条件下发生，以良好的产率得到2-（2-羟乙基）-1,3-二芳基丙烯酮。通过用三乙基甲硅烷基（TES）保护羟基，以高收率和良好的几何选择性获得了相应的开环产物7。
