• Regioselective dihydropyran formation from 4-iodo-2,6-disubstituted tetrahydropyran derivatives using In(OAc)3/LiI system as the promoter

  The rapid and regioselective synthesis of a series of 2,6-disubstituted dihydropyranic building-blocks bearing an oxygenated side chain is described. The corresponding 4-iodo tetrahydropyran precursors, easily prepared by Prins cyclization, underwent regioselective elimination in the presence of an In(OAc)3/LiI system to provide the title compounds. The one-pot Prins cyclization-elimination process

  method for a directed stereoselective guanidinylation of alkenes is described. The guanidine unit can be delivered as an intact fragment by a hydroxy or carboxy group, usually with a high level of stereocontrol. After the guanidine delivery, the directing group can be cleaved under exceptionally mild conditions, typically by alcoholysis in the presence of acetic acid. Broad functional group tolerance

  描述了用于烯烃的定向立体选择性胍基化的方法。胍单元可以通过羟基或羧基作为完整片段递送，通常具有高水平的立体控制。胍基递送后，可以在异常温和的条件下，通常通过在乙酸的存在下进行醇解，来切割该导向基团。宽泛的官能团耐受性和环胍基化的温和反应条件表明其在药物化学和天然产物合成中的应用。

  [reaction: see text] A new version of the Mukaiyama aldol-Prins (MAP) cyclization has been developed. Unsaturated enol ethers such as 3 were found to couple with aldehydes in the presence of TiBr(4) to give 4-bromotetrahydropyran products. This cascade reaction sequence leads to the formation of two new carbon-carbon bonds, a ring, and three new stereogenic centers. We expect this reaction to be a

  A simple enzymatic method for the preparation of optically active 1,2- and 1,3-diol derivatives is disclosed. In the screening of enzymes, racemic 4-[(2-benzyloxy)ethyl]-1,3-dioxolan-2-one (1a) was enantioselectively hydrolyzed by porcine pancreas lipase (PPL) to give optically active (R)-1a and (S)-4-(benzyloxy)butane-1,2-diol (2a). The addition of 10% i-Pr2O to the reaction system dramatically improved
