  Spiroligozymes for Transesterifications: Design and Relationship of Structure to Activity

  摘要：

  Transesterification catalysts based. on stereochemically defined, modular, functionalized ladder-molecules (named spiroligozymes) were designed, using the "inside-out" design strategy, and mutated synthetically to improve catalysis. A series of stereochemically and regiochemically diverse bifunctional spiroligozymes were first synthesized to identify the best arrangement of a pyridine as a general base catalyst and an alcohol nucleophile to accelerate attack on vinyl trifluoroacetate as an electrophile. The best bifunctional spiroligozyme reacted with vinyl trifluoroacetate to form an acyl-spiroligozyme conjugate 2.7 X 10(3)-fold faster than the background reaction with a benzyl alcohol. Two trifunctional spiroligozymes were then synthesized that combined a urea with the pyridine and alcohol to act as an oxyanion hole and activate the bound acyl-spiroligozyme intermediate to enable acyl-transfer to methanol. The best trifunctional spiroligozyme carries out multiple turnovers and acts as a transesterification catalyst with k(1)/k(uncat) of 2.2 X 10(3) and k(2)/k(uncat) of 1.3 X 10(2). Quantum mechanical calculations identified the four transition states of the catalytic cycle and provided a detailed view of every stage of the transesterification reaction.

  acids are chiral, cyclic building blocks that display two alpha-amino acids that are differentiated from each other with protecting groups. They are assembled into spiroligomers—rigid, shape-programmable spirocyclic oligomers that are both stereochemically and functionally diverse. The synthesis presented here focuses on recent improvements that allow for a convenient, large-scale synthesis of twelve

  反式-4-羟基-1-脯氨酸衍生的双氨基酸是手性的环状结构单元，显示出两个带有保护基的α-氨基酸。它们被组装成螺线低聚物—刚性，形状可编程的螺环低聚物，在立体化学和功能上都不同。这里提出的合成集中在最近的改进上，这些改进允许从便宜的反式-4-羟基-1-脯氨酸方便，大规模地合成十二种立体化学纯的双氨基酸。双氨基酸在立体化学上和胺保护基上有所不同，其中一个（对硝基苄基氨基甲酸酯）以前没有被掺入双氨基酸中。
• Synthesis of Spiroligomer-Containing Macrocycles

  We demonstrate the synthesis and characterization of the solution conformations of a collection of functionalized spiroligomer-based macrocycles. These macrocycles contain 14 independently controllable stereocenters and four independently controllable functional groups on a highly preorganized scaffold. These molecules are being developed to display complex, preorganized surfaces for binding proteins and to create enzyme-like active sites. In this work, we demonstrate the convergent synthetic approach to this new class of macrocycles and demonstrate that the conformational properties of these molecules can be changed by altering the configuration stereocenters within the backbone.
