IMDA cycloadditions of 3-alkynyl tethered 2-pyrones for the synthesis of medium-sized macrocycles
摘要:
Alkynyl tethered 2-pyrones underwent intramolecular Diels-Alder cycloadditions to provide bicyclolactone-fused medium-sized macrocycles in good overall yields. Lactone ring opening reactions furnished various ring fused medium-sized macrolactams and macroazanes with good overall yields. (C) 2004 Elsevier Ltd. All rights reserved.

researched area of polymer chemistry. Herein, we report the synthesis and characterization of 2-(1-(2-(diethoxyphosphoryl)ethyl)-1H-1,2,3-triazol-4-yl)ethyl acrylate (M1) and diethyl (2-(4-(2-acrylamidoethyl)-1H-1,2,3-triazol-1-yl)ethyl)phosphonate (M2) monomers using the copper-catalyzed azide–alkyne cycloaddition (CuAAC) ‘click’ reaction, and their subsequent polymerization via both uncontrolled and
这项研究的目的是开发新型的含膦酸酯的聚合物,因为它们仍然是聚合物化学领域中一个相对尚未被研究的领域。在这里,我们报道了丙烯酸2-(1-(2-(二乙氧基磷酰基)乙基)-1 H -1,2,3-三唑-4-基)乙基丙烯酸酯(M1)和二乙基(2-(4 -(2-丙烯酰胺基乙基)-1 H -1,2,3-三唑-1-基)乙基)膦酸酯(M2)单体,使用铜催化的叠氮化物-炔烃环加成(CuAAC)的“点击”反应及其后续聚合通过既不受控制的和可逆加成-断裂链转移(RAFT)聚合技术得到的膦酸酯的聚合物(P1 - P4)。
Screening of a glycopolymer library for GM1 mimetics synthesized by the “carbohydrate module method”
This work demonstrates a facile and fast screening of glycopolymers for the “carbohydrate module method” by a combination of photoinduced living polymerization and surface plasmon resonance imaging.
Molecular mobility is important for interactions of biofunctional polymers with target molecules. Monomerstructures for synthetic biofunctional polymers are usually selected based on their compatibility with polymerization systems, whereas the influence of monomerstructures on the interaction with target molecules is hardly considered. In this report, we evaluate the correlation between the monomer
分子迁移率对于生物功能聚合物与目标分子的相互作用很重要。合成生物功能聚合物的单体结构通常是根据它们与聚合体系的相容性来选择的,而单体结构对与目标分子相互作用的影响几乎没有考虑。在本报告中,我们评估了糖聚合物的单体结构与其与刀豆蛋白 A (ConA) 相互作用的分子流动性之间的相关性。两种类型的含甘露糖的糖聚合物是用丙烯酰胺或丙烯酸酯单体合成的。尽管结构相似,除了侧链中的酰胺键或酯键,在等温滴定量热法测量和血凝抑制试验中,丙烯酸酯型糖聚合物与 ConA 表现出更强的相互作用。丙烯酸酯型糖聚合物的表征表明,较高的结合常数源于甘露糖单元的较高分子迁移率,这是由于其侧链中酯键的旋转自由度所致。
