International Classification:

C07D21516

US Classification:

546153, 546167, 546180

Abstract:

The invention relates to a process for preparing quinoline-substituted carbonate and carbamate compounds, which are important intermediates in the synthesis of 6-O-substituted macrolide antibiotics. The process employs metal-catalyzed coupling reactions to provide a carbonate or carbamate of formula (I) or (II) or a substrate that can be reduced to obtain the same.

Assignee:

Guardian Industries, Inc. - Auburn Hills MI

International Classification:

B32B 2708

US Classification:

428 31, 428421, 428520, 428522, 428523

Abstract:

Laminates include a thermoplastic substrate layer, a clear coat layer, and a tie layer. The tie layer most preferably includes an adhesive-enhancing effective amount of a thermoplastic reactive terpolymer of ethylene-methyl acrylate-glycidyl methacrylate (E-MA-GMA) which adhesively bonds the substrate and clear coat layers one to another. Most preferably, the tie layer is a blend of E-MA-GMA and a tackifier (e. g. , a C6-C8 cycloaliphatic hydrocarbon resin). The laminate may be employed to manufacture a variety of shaped articles, most preferably automotive trim components.

Abstract:

Laminates include a thermoplastic substrate layer, a clear coat layer, and a tie layer between the substrate and clear coat layers. The tie layer most preferably includes a first layer adjacent the thermoplastic substrate layer which is comprised of a polyolefin, and a second layer adjacent to the clear coat layer which is comprised of a polyamide. Most preferably, the substrate layer is TPO and the clear coat layer is PVF. The laminates may be employed to manufacture a variety of shaped articles, most preferably automotive trim components.

Abstract:

Laminates include a thermoplastic substrate layer, a clear coat layer, and a tie layer. The tie layer most preferably includes an adhesive-enhancing effective amount of a maleic anhydride grafted styrenic block copolymer which adhesively bonds the substrate and clear coat layers one to another. Advantageously, the tie layer includes a blend of the styrenic block copolymer and a diamine, especially 2-methylpentamethylenediamine. The laminate may be employed to manufacture a variety of shaped articles, most preferably automotive trim components.

International Classification:

C07D 498/18

US Classification:

514291, 540456

Abstract:

A single-step, one-pot process to obtain zotarolimus and other rapamycin derivatives on large scale is presented, which improves currently available synthesis schemes. In one embodiment, dried rapamycin is dissolved in isopropylacetate (IPAc). The solution is cooled, and 2,6-Lutidine is added, followed slowly adding triflic anhydride at −30 C. Salts are then removed by filtration. Tetrazole, followed by a tert-base diisopropylethylamine (DIEA) is added to the triflate solution. After incubation at room temperature, the product is concentrated and purified by a silica gel column using THF/heptane as eluant. The fractions containing the product are collected, concentrated, and purified again using an acetone/heptane column. The product containing fractions are concentrated. The product is dissolved in t-BME and precipitated with heptane.
