  Design and Synthesis of 4-(α-Hydroxymalonyl)phenylalanine as a New Phosphotyrosyl Mimetic and Its Use in Growth Factor Receptor Bound 2 Src-Homology 2 (Grb2 SH2) Domain-Binding Peptides

  摘要：

  A new phosphotyrosyl mimetic 4-(alpha-hydroxymalonyl)phenylalanine and its incorporation into a Grb2 SH2 domain-binding tripeptide are presented. In whole-cell studies using malonyl ethyl ester prodrug derivatives, it was observed that the 4-(alpha-hydroxymalonyl)phenylalanyl-containing peptide exhibited greater efficacy than the nonhydroxylated 4-(malonyl)phenylalanyl-containing congener in blocking the association of Grb2 with activated erbB-2 tyrosine kinase. These results are consistent with de-esterification and at least partial intracellular decarboxylation.

  Guided by the mechanistic insights from computational studies, we have developed an Ir‐catalyzed asymmetric intramolecular allylic dearomatization reaction of benzene derivatives. Under the optimized conditions consisting of a readily available Ir catalyst, a series of spiro[4.5]cyclohexadiene compounds were delivered in reasonable yields (up to 79 %) with good enantioselectivity (up to 99 % ee). The

  在计算研究的力学见解的指导下，我们开发了苯衍生物的Ir催化不对称分子内烯丙基烯丙基脱芳香化反应。在由易于获得的Ir催化剂组成的优化条件下，以合理的收率（最高79％）和良好的对映选择性（最高99％ee）提供了一系列螺[4.5]环己二烯化合物。丙二酸酯二酯型取代基的引入是指导苯环亲核反应性的关键策略。
