    Thiolane-2,4-dione 和衍生物的碱诱导光反应的多样性。碳骨架的还原环解理和新的重排
    摘要:
    在碱存在的情况下,在甲醇中对硫戊环-2,4-二酮(硫代特酮酸)及其衍生物 1a-1d 进行辐照诱导还原性环裂解,生成 β,β'-二酮酯。在非质子溶剂(如乙腈或丙酮)中也观察到碱诱导的还原环裂解,尽管在这些情况下获得的产物是 β,β'-二酮酰胺。另一方面,在碱存在的情况下,在水中照射 1a-1d 会引起碳骨架的重排,生成琥珀酸硫酐、γ-酮酰胺或琥珀酰胺以及还原产物。当吡啶用作水中光解的碱时,两种 3-乙酰基衍生物 1a 和 1b 产生 γ-酮硫醇和相应的二硫化物,这是由另一种类型的碳骨架重排产生的。

  • CONTACT-KILLING, QAC FUNCTIONALIZED THERMOPLASTIC POLYURETHANE FOR CATHETER APPLICATIONS
    申请人:The University of Akron
    公开号:EP3508510A1
    公开(公告)日:2019-07-10
    In various embodiments, the present invention provides a functionalized thermoplastic polyurethane (TPU) containing bulk incorporated or surface-grafted quaternary ammonium compounds (QAC)s for contact-killing of a variety of microbes, where the QACs are on the surface of TPU to provide a sterile surface material that prevents bacteria commonly involved in device-associated infections (DAIs) from proliferating. The functionalized TPUs of the present invention can be formed into a wide variety of 3-dimensional shapes, such as catheters, medical tubing, laryngeal or tracheal stents, sutures, prosthetics, wound dressings, and/or a coating for medical devices and contains the residue of either a QAC containing diol monomer or an alkene functional diol monomer, which then allows the TPU to be functionalized with a QAC containing disulfide or free thiol compound, to form a quaternary ammonium functionalized thermoplastic polyurethane compound having antimicrobial properties for use in medical devices.
