    二羧酸的催化剂控制位点选择性亚甲基CH内酯化。
    摘要:
    游离羧酸的β-和γ-亚甲基碳氢(CH)键的催化剂控制的位点选择性活化是一个长期存在的挑战。在这里,我们表明,通过一对由不同螯合环尺寸的喹啉-吡啶酮配体组装的钯催化剂,可以与多种二羧酸进行高度位点选择性的单内酯化反应,产生结构多样且合成上有用的γ-和δ-内酯通过位点选择性β-或γ-亚甲基CH活化。剩余的羧基可作为进一步合成应用的多功能关键,如从丰富的二羧酸中全合成两种天然产物 myrotheciumone A 和pedicellosine 所证明的那样。

    The present invention relates to a reusable print medium comprising a substrate and a sacrificial layer. The sacrificial layer contains a hotmelt composition at least comprising an amorphous material. The amorphous material is a resin being a reaction product of a first monomer A, said first monomer A being a polyhydroxyl alcohol comprising X hydroxyl functional groups, wherein X≧2, monomer A optionally comprises a primary or secondary amine functionality; a second monomer B, being an aromatic monocarboxylic acid; a third monomer C, said third monomer C being able to form an ester linkage with an alcohol and/or an amide linkage with a primary or secondary amine; and optionally, a fourth monomer D, being an aromatic monocarboxylic acid different from the second monomer B. The sacrificial layer including the printed image may be removed from the substrate by applying heat. A new sacrificial layer may be applied such that the reusable print medium is ready to be reused. The present invention also relates to a method of manufacturing a reusable print medium according to the present invention, a method of printing and recycling such a print medium and an apparatus for printing and recycling such a print medium.

    公开(公告)日:1982-05-26
    High molecular weight copolymers containing β-hydroxybutyric acid residue, i.e. units of the formula and up to 50 mole % of residues of other hydroxy acids, viz units of the formula where n is 0 or 1 and, if n = 1 and R2, R3, and R4 = H, R2 is not methyl. The copolymers are made microbiologically: for part of the cultivation the micro-organism is under conditions of limitation of a nutrient, e.g. nitrogen source, required for growth but not polyester accumulation. For at least part of this period of growth limitation the substrate is an acid or a salt thereof that tives the comonomer units. Propionic acid, which gives polymers where n = 1, R2=R3=R4=H and R1= C2H2, is the preferred acid.
