• Rate Acceleration of the Baylis−Hillman Reaction in Polar Solvents (Water and Formamide). Dominant Role of Hydrogen Bonding, Not Hydrophobic Effects, Is Implicated

  A substantial acceleration of the Baylis-Hillman reaction between cyclohexenone and benzaldehyde has been observed when the reaction is conducted in water. Several different amine catalysts were tested, and as with reactions conducted in the absence of solvent, 3-hydroxyquinuclidine was found to be the optimum catalyst in terms of rate. The reaction has been extended to other aldehyde electrophiles

  当反应在水中进行时，已观察到环己烯酮和苯甲醛之间的Baylis-Hillman反应大大加速。测试了几种不同的胺催化剂，并且与在不存在溶剂的情况下进行的反应一样，就速率而言，发现3-羟基喹核苷是最佳催化剂。该反应已经扩展到包括醛的其他醛亲电试剂。尝试将这项工作扩展至丙烯酸酯仅获得了部分成功，因为在碱催化和水促进的条件下，丙烯酸甲酯和丙烯酸乙酯迅速水解。然而，丙烯酸叔丁酯足够稳定以与相对反应性的亲电试剂偶联。有关使用极性溶剂的进一步研究表明，甲酰胺还提供了显着的加速作用，并且使用5当量的甲酰胺（最适量）比在水中进行的反应速率更快。使用甲酰胺，在Yb（OTf）（3）（5 mol％）的存在下实现了进一步的加速。新条件的范围用一系列迈克尔受体和苯甲醛以及一系列亲电试剂和丙烯酸乙酯进行了测试。讨论了速率加速的起源。
• Vinylalumination for the Synthesis of Functionalized Allyl Alcohols, Vinylepoxides, and α-Alkylidene-β-hydroxy-γ-lactones
  作者：P. Veeraraghavan Ramachandran、Michael T. Rudd、Thomas E. Burghardt、M. Venkat Ram Reddy

  A modified hydroalumination protocol for the preparation of [alpha-(ethoxycarbonyl)vinyl]diisobutyl-aluminum and its beta-methyl or -phenyl analogues was developed. These vinylaluminum reagents react with aldehydes and ketones to provide the corresponding functionalized allyl alcohols in good to excellent yields. Perfluoroalkyl and -aryl carbonyl compounds, alpha-keto esters, alpha-acyl cyanides, and alpha-acetylenic ketones provide the corresponding alpha-hydroxyalkenes in high yields. The allyl alcohol product ratios from the vinylalumination of unsymmetrical alpha-diketones with [alpha-(ethoxycarbonyl)vinyl] diisobutylaluminum and its beta-methyl or -phenyl analogues depend on the steric and electronic environments of the ketones as well as the reagents. The products from the vinylalumination of alpha-bromoaldehydes and -ketones were cyclized With K2CO3 or KF under nonaqueous conditions to provide functionalized vinylepoxides in high yields. Vinylaluminations of keto-protected pyruvaldehyde provided the products, which were converted to alpha-alkylidene-beta-hydroxy-gamma-lactones.

  Ethyl acrylate and acrylonitrile fail to undergo efficient Baylis-Hillman reaction with fluoral, but provide good yields of products with pentafluorobenzaldehyde. Alternately, unsubstituted and beta-substituted [alpha- (ethoxycarbonyl)vinyl]aluminum react with perfluoroalkyl and -aryl aldehydes and ketones to provide the alpha-hydroxyalkenylated fluoroorganic compounds in good to excellent yields.
