  Enantioselective synthesis of cis-7-methoxy-calamenene via Claisen rearrangement of an enzymatically resolved allyl alcohol

  摘要：

  An enantioselective synthesis of cis-7-methoxy-calamenene 1 has been accomplished through the following key-steps: (i) enzymatic resolution of the racemic allyl alcohol 3 to furnish the (R)-enantiomer (ee >99%); (ii) Claisen-orthoester rearrangement of 4 to introduce the isopropyl unit on the benzylic position (99% ee); (iii) diastereoselective reduction of dihydronaphthalene derivative 11 to give the cis-isomer 12 (98% de); (iv) regioselective introduction of the formyl group by a Vilsmeier reaction followed by reduction to give 1.

  通过脂酶-钒组合催化一锅法合成旋光烯丙基酯

  摘要：

  钒-氧代化合物（3或4）与脂肪酶的组合产生了外消旋烯丙醇（1或2）向光学和活性烯丙基酯的区域和对映体转化。在该系统中，钒化合物催化醇的连续外消旋化以及羟基的转位，而脂肪酶则实现化学和对映选择性酯化反应，以实现动态动力学拆分。

  tests in the racemization of (S)-4-phenyl-2-butanol showed that 7 is the most active catalyst, although the difference decreased in the DKR. Complex 4 was used in the DKR of various alcohols; at room temperature, not only simple alcohols but also functionalized ones such as allylic alcohols, alkynyl alcohols, diols, hydroxyl esters, and chlorohydrins were successfully transformed to chiral acetates.

  The palladium catalyzed regio- and diastereo-selective allylic alkylation of (R)-2-acetoxy-4-aryl-3-butene with N-(diphenylmethylidene)glycinate and N-(diphenylmethylidene)alaninate occurred. The stereochemistry was controlled by the use of o-(diphenylphosphino)carboxylic acid, and produced new amino acid derivatives possessing vicinal chiral quaternary and tertiary carbon centers at the α and β positions

  A continuous-flow dynamic kinetic resolution of racemic secondary alcohols was carried out using a single column reactor packed with a mixture of immobilized lipase and an immobilized oxovanadium species, VMPS4. As a result, optically pure esters were produced in 88–92 % yields. Problems encountered in this study were overcome by using fillers that efficiently
