    日期:1979.1
    The reaction between tertiary α-bromo ketones or aldehydes and silver tetrafluoroborate in ether affords α-fluorocarbonyl compounds. Neighboring group participation by the carbonyl oxygen is proposed to account for the products and by-products.

    One aspect of the present invention generally relates to methods of sealing a wound or tissue plane or filling a void splace. In a preferred embodiment, the wound is an ophthalmic, pleural or dural wound. In certain instances, the compositions used to seal the wound or tissue plane comprises a polyalkyleneamine. In a preferred embodiment, the polyalkyleneamine is polyethyleneimine. Treatment of the polyethyleneimine with a cross-linking reagent causes the polyethyleneimine polymers to polymerize forming a seal. In certain instances, the cross-linking reagent is a polyethylene glycol having reactive terminal groups. In certain instances, the reactive terminal groups are activated esters, such as N-hydroxy succinimide ester. In certain instances, the reactive terminal groups are isocyanates. In certain instances, the polyethyleneimine has a lysine, cysteine, isocysteine or other nucleophilic group attached to the periphery of the polymer. In certain instances, the polyethyleneimine is mixed with a second polymer, such as a polyethylene glycol containing nucleophilic groups. In certain instances, the compositions used to seal the wound or tissue plane are formed by reacting a polyalkyleneamine bearing electrophilic groups with a cross-linking reagent containing nucleophilic groups. In certain instances, the electrophilic groups on the polyalkyleneamine are activated esters, such as N-hydroxy succinimide ester. In certain instances, the compositions used to seal the wound or tissue plane are formed by reacting a polyalkyleneamine bearing photopolymerizable groups with ultraviolet or visibile light. Compositions used to seal the wound which contain PEI or a derivative of PEI are found to adhere tightly to the tissue. Other aspects of the present invention relate to methods of filling a void of a patient or adhering tissue. In certain instances, the methods use a polyalkyleneamine. In a preferred embodiment, the polyalkyleneamine is polyethyleneimine. Another aspect of the present invention relates to a polymeric composition formed by exposing a polyalkyleneamine to an activated polyalkylene glycol. In certain instances, the composition is attached to mammalian tissue.
    本发明的一个方面通常涉及封闭伤口或组织平面或填充空隙的方法。在一个优选实施例中,伤口是眼科、胸膜或硬脑膜伤口。在某些情况下,用于封闭伤口或组织平面的组合物包括聚烷胺。在一个优选实施例中,聚烷胺是聚乙烯亚胺。用交联试剂处理聚乙烯亚胺会导致聚乙烯亚胺聚合物聚合形成密封。在某些情况下,交联试剂是具有反应末端基团的聚乙二醇。在某些情况下,反应末端基团是活化酯,如N-羟基琥珀酰亚胺酯。在某些情况下,反应末端基团是异氰酸酯。在某些情况下,聚乙烯亚胺具有赖酸、半胱酸、异半胱酸或其他亲核基团附着在聚合物的周边。在某些情况下,聚乙烯亚胺与第二聚合物混合,如含有亲核基团的聚乙二醇。在某些情况下,用于封闭伤口或组织平面的组合物是通过将具有亲电子基团的聚烷胺与含有亲核基团的交联试剂反应形成的。在某些情况下,聚烷胺上的亲电子基团是活化酯,如N-羟基琥珀酰亚胺酯。在某些情况下,用于封闭伤口或组织平面的组合物是通过将具有光聚合基团的聚烷胺与紫外光或可见光反应形成的。发现含有PEI或PEI衍生物的用于封闭伤口的组合物能够紧密粘附在组织上。本发明的其他方面涉及填充患者空隙或粘附组织的方法。在某些情况下,这些方法使用聚烷胺。在一个优选实施例中,聚烷胺是聚乙烯亚胺。本发明的另一个方面涉及通过将聚烷胺暴露于活化聚乙烯醇而形成的聚合物组合物。在某些情况下,这种组合物附着在哺乳动物组织上。
