  Cycloaddition/Ring opening of 3-unsubstituted cyclic nitronates, isoxazoline and 5,6-dihydro-4H-1,2-oxazineN-oxides, as synthetic equivalents of functionalized nitrile oxides

  摘要：

  omega-Halo-alpha-nitropropane and -butane are cyclized with a base to form cyclic nitronates as labile 1,3-dipoles. They can be trapped by a variety of monosubstituted ethenes to give 3-(2-hydroxyethyl)isoxazolines or perhydroisoxazolo[2,3-b]o-oxazines depending upon the ring size of nitronates. The latter ring-fused heterocycles are transformed by treatment with an acid into 3-(3-hydroxypropyl)isoxazolines in good yields. Therefore, these cyclic nitronates are useful synthetic equivalents of functionalized nitrile oxides. Isolation of 5,6-dihydro-4H-1,2-oxazine N-oxide and their regio- and stereoselective cycloadditions are also discussed. (C) 1998 Elsevier Science Ltd. All rights reserved.

  聚异恶唑啉的固相组合合成：两个反应的迭代方案。

  摘要：

  从与聚合物结合的烯烃开始，反复应用腈氧化物1,3-偶极环加成和硒化物氧化/消除步骤，以递送可以通过酯交换反应从树脂中释放出来的与聚合物结合的三异恶唑啉。当使用四个硝基硒代醚（2-5）和四个封端硝基烷烃（6-9）时，通过这两个反应的三个迭代应用，获得了具有64个位置异构体的三异恶唑啉文库（V）。这种制备小型多官能低聚物的策略在战术上的灵活性特别吸引人，因为每个亚基的添加均通过CC键形成步骤进行。

  In 2003, we reported the isolation, structure elucidation, and pharmacology of epiquinamide (1), a novel alkaloid isolated from an Ecuadoran poison frog, Epipedobates tricolor. Since then, several groups, including ours, have undertaken synthetic efforts to produce this compound, which appeared initially to be a novel, beta 2-selective nicotinic acetylcholine receptor agonist. Based on prior chiral GC analysis of synthetic and natural samples, the absolute structure of this alkaloid was established as (1S,9aS)-1-acetamidoquinolizidine. We have synthesized the (1R*,9aS*)-isomer (epi-epiquinamide) using an iminium ion nitroaldol reaction as the key step. We have also synthesized ent-1 semisynthetically from (-)-lupinine. Synthetic epiquinamide is inactive at nicotinic receptors, in accord with recently published reports. We have determined that the activity initially reported is due to cross-contamination from co-occurring epibatidine in the isolated material.

  Starting from a polymer-bound olefin, iterative application of nitrile oxide 1,3-dipolar cycloaddition and selenide oxidation/elimination steps were employed to deliver a polymer-bound triisoxazoline that can be liberated from the resin by transesterification. When four nitroseleno ethers (2-5) and four capping nitroalkanes (6-9) were employed, a triisoxazoline library (V) of 64 positional isomers
