  几丁质合酶抑制剂C-糖基核苷的合成与评价

  摘要：

  作为我们正在进行的旨在抑制几丁质合酶的计划的一部分，我们已经制备了一种新的C-糖基核苷作为UDP-GlcNAc的代谢稳定底物类似物。合成策略依赖于核苷和氨基C-糖基部分与L-酒石酸的连续偶联。但是，该化合物仅抑制弱几丁质合酶I，IC（50）值为20 mM。

  The convergent synthesis of a new class of chiral dendrimers is described. Owing to their structural resemblance to depsipeptides they are called depsipeptide dendrimers. The ex-chiral pool synthesis starts from (R,R)-, (S,S)-, and meso-tartaric acid as branching units and dipeptides or tripeptides consisting of glycine, (L)-alanine, and (L)-leucine as chiral-spacer building blocks. The key intermediates

  描述了新型手性树状聚体的收敛合成。由于它们与大肽肽的结构相似，它们被称为大肽肽树状聚合物。前手性池的合成起始于（R，R）-，（S，S）-和内消旋酒石酸作为分支单元以及由甘氨酸，（L）-丙氨酸和（L）-亮氨酸组成的二肽或三肽作为手性垫片的组成部分。这种二肽树状大分子聚合组装的关键中间体是肽-酒石酸共轭物13a，b，19a，b，25和27，其中包含一个未保护的肽链C末端（13a，b，25）或酒石酸末端的两个未保护的羟基。通过使用立体异构结构单元的不同组合，合成了第三代的丹德拉，并对其进行了完全表征。
• Solid-state and solution conformational analysis of tartrate-derived 1,3-dioxolanes and 1,3,2-dioxaborolanes

  Solid-state (X-ray) and solution conformational analyses of tartrate ester derived 1,3-dioxolanes and 1,3,2-dioxaborolanes are described. The solid-state conformation of dimethyl benzylidenetartrate (5) was found to be one in which the two carbomethoxy groups are pseudoaxial and the ester carbonyls eclipse the adjacent dioxolane C-O bonds. This parallels exactly the conformation previously proposed for the 1,3,2-dioxaborolane unit in the transition state of the reactions of tartrate ester modified allylboronates 1-3 and aldehydes. A correlation was developed between the solution and solid-state conformations of 1,3-dioxolanes 5-7 based on the observed J4,5 coupling constants and the H-4-C-C-H-5 dihedral angle obtained from the X-ray crystal structures. A high resolution variable-temperature H-1 NMR study of 1,3-dioxolane 5 in THF-d8 revealed that J4,5 decreased from 3.72 Hz at 23-degrees-C to 2.91 Hz at -80-degrees-C, providing evidence that the diaxial conformation is increasingly favored as the temperature is decreased. A high resolution variable-temperature H-1 NMR study of ortho ester 12, prepared from dimethyl tartrate and trimethyl orthoacetate, in THF-d8 similarly revealed J4,5 = 5.25 Hz at 23-degrees-C and J4,5 = 4.60 Hz at -80-degrees-C. An analogous solution conformation analysis was also performed with 1,3,2-dioxaborolane derivatives 16 and 17 prepared from methyl trifluoroethyl tartrate (15). Variable-temperature H-1 NMR analysis of 17 in toluene-d8 revealed that J4,5 decreased to a value of J4,5 = 5.0 Hz at 23-degrees-C to J4,5 = 4.3 Hz at -60-degrees-C. The significance of these data to the mechanism of asymmetric induction in the reactions of the tartrate ester modified allylboronates 1-3 and aldehydes is discussed.
