  Tandem cross-Rauhut–Currier/cyclization reactions of activated alkenes to give densely functionalized 3,4-dihydropyrans

  摘要：

  A novel tandem cross-Rauhut-Currier/cyclization reaction between alpha,beta-unsaturated ketones was developed. Using DABCO (20 mol %) as the catalyst, a series of densely functionalized 3,4-dihydropyrans were obtained in excellent yields and stereoselectivities (up to 98% yield, >99:1 dr). A tentative catalytic cycle was proposed with key intermediates confirmed by ESIMS studies. (C) 2011 Elsevier Ltd. All rights reserved.

  日期：——

  DABCO catalyzed the cross-Rauhut–Currier/transesterification reaction of α-cyano-α,β-unsaturated ketones and aryl acrylates was discovered. The reaction rate law was determined by an integral method under pseudo-first-order reaction conditions, which assisted in proposing the mechanism of cross-Rauhut–Currier reaction promoted by Brønsted acid and establishing the rate-determining step.

  发现 DABCO 催化 α-氰基-α、β-不饱和酮和丙烯酸芳基酯的交叉 Rauhut 柯里尔/酯交换反应。在准一级反应条件下，采用积分法确定了反应速率规律，有助于提出布伦斯台德酸促进的交叉Rauhut-柯里尔反应的机理，并建立了速率决定步骤。
