  Chemoenzymic preparation of asymmetrized tris(hydroxymethyl)methane (THYM*) and of asymmetrized bis(hydroxymethyl)acetaldehyde (BHYMA*) as new highly versatile chiral building blocks

  摘要：

  A series of asymmetrized tris(hydroxymethyl)methanes 2 and bis(hydroxymethyl)acetaldehydes 3 have been prepared in both enantiomeric forms through a chemoenzymatic methodology. The key step is the highly enantioselective PPL-catalyzed monohydrolysis of 2(E)-alkenyl-1,3-diacetoxypropanes 25-27. A careful study on the effect of unsaturations adjacent to the prochiral center in a series of 2-substituted 1,3-diacetoxypropanes has confirmed the suggested beneficial effect of a pi-system in that position but has also unveiled an unprecedented dramatic effect of double-bond configuration on enantioselectivity. A new empirical model for the interpretation of these and other results, based both on polarity and steric arguments, is proposed. This study provides a general protocol for the efficient synthesis of asymmetrized 1,3-propanediols bearing in position 2 saturated or unsaturated carbon chains.

  通过三羰基铁-内酯配合物制备内酯

  摘要：

  通过五羰基铁的处理，已经从乙烯基环氧乙烷中制备了许多三羰基铁-内酯配合物。在某些情况下，两个η 3 -烯丙基配合物进行了从单一乙烯基环氧乙烷分离。硝酸铈（IV）铵在乙腈中对络合物的氧化主要导致β-内酯。初始配合物的立体化学完整性反映在氧化产物的形成中。用氢化铝锂还原这些产物得到预期的二醇。

• A Short Access to 3-Hydroxy-4-hydroxymethyltetrahydrofurans: Application to the Total Synthesis of Amphiasterin B4

  日期：2009.3.6

  The first total synthesis of amphiasterin B4, a secondary metabolite previously isolated from Plakortisquasiamphiaster has been achieved. The core structure has been reached according to a highly stereoselective one-pot epoxidation/cyclization of an unsaturated diol. This substrate can be prepared from β,γ-unsaturated diesters readily available from the organocatalyzed protonation of a transient dienol

  已经完成了两性代谢物amphiasterin B4的首次合成，后者是先前从Plakortis quasiamphiaster中分离出来的次级代谢产物。根据不饱和二醇的高度立体选择性的一锅环氧化/环化，已经达到了核心结构。该底物可以由β，γ-不饱和二酯制备，所述β，γ-不饱和二酯可容易地得自通过相应的α，β-不饱和异构体的UV辐射而产生的过渡二烯醇的有机催化质子化。
