  • An efficient synthesis of (E)-α,β-unsaturated ketones and esters with total stereoselectivity by using chromium dichloride
    作者:José M. Concellón、Humberto Rodríguez-Solla、Carmen Méjica
    DOI:10.1016/j.tet.2006.01.052
    日期:2006.4
    (E)-α,β-Unsaturated ketones 1 or esters 2 can be obtained with complete stereoselectivity by reaction of different 2-chloro-3-hydroxy ketones 3 or esters 4 and CrCl2. A comparative study of the results of synthesis of ketones 1 with CrCl2 or samarium is performed. A mechanism to explain both β-elimination reactions has been proposed.

    Matrix metalloproteinases (MMps) are a group of enzymes that have been implicated in the pathological destruction of connective tissue and basement membranes. These zinc containing endopeptidases consist of several subsets of enzymes including collagenases, stromelysins and gelatinases. TNF-&agr; converting enzyme (TACE), a pro-inflammatory cytokine, catalyzes the formation of TNF-&agr; from membrane bound TNF-&agr; precursor protein. It is expected that small molecule inhibitors of MMPs and TACE therefore have the potential for treating a variety of disease states. The present invention provides low molecular weight, non-peptide inhibitors of matrix metalloproteinases (MMPs) and TNF-&agr; converting enzyme (TACE) for the treatment of arthritis, tumor metastasis, tissue ulceration, abnormal wound healing, periodontal disease, bone disease, diabetes (insulin resistance) and HIV infection. The compounds of this invention are represented by the formula where R1, R2, R3 and R4 are described herein.

  • Oxidation of Diols and Ethers by NaBrO<sub>3</sub>/NaHSO<sub>3</sub>Reagent

    NaBrO3 combined with NaHSO3 was found to be an excellent oxidizing reagent of alcohols, diols, and ethers under mild conditions. A variety of aliphatic and cyclic diols were selectively oxidized with satisfactory yields to the corresponding hydroxy ketones and/or diketones, which are difficult to selectively prepare due to a concomitant formation of cleaved products. For example, 2-hydroxycyclohexanone and 1,2-cyclohexanedione were selectively formed by allowing 1,2-cyclohexanediol to react with NaBrO3/NaHSO3 reagent in a selected solvent. On the other hand, an alkyl ether, such as dioctyl ether, reacted with NaBrO3/NaHSO3 in water at room temperature to give octyl octanoate in 82% yield. The same oxidation at higher temperature (60 °C) produced the α-brominated ester, octyl 2-bromooctanoate, which is considered to be formed through an alkenyl alkyl ether as the intermediate. The treatment of 1-ethoxy-1-heptene with NaBrO3/NaHSO3 afforded ethyl 2-bromoheptanoate and 2-bromoheptanoic acid as the major products.
    NaBrO3与NaHSO3组合被发现是一种在温和条件下对醇、二醇和醚类具有优异氧化能力的试剂。多种脂肪族和环状二醇被选择性地氧化为相应的羟基酮和/或二酮,产率令人满意,这些产物由于伴随生成断裂产物而难以选择性制备。例如,通过在选定溶剂中使1,2-环己二醇与NaBrO3/NaHSO3试剂反应,选择性地生成了2-羟基环己酮和1,2-环己二酮。另一方面,在室温下,二辛醚在水中的NaBrO3/NaHSO3反应以82%的产率得到了辛基辛酸酯。同样的氧化反应在较高温度(60°C)下产生了α-溴代酯,即辛基2-溴辛酸酯,这被认为是通过烯基烷基醚作为中间体形成的。使用NaBrO3/NaHSO3处理1-乙氧基-1-庚烯,主要产物是乙基2-溴庚酸酯和2-溴庚酸。

    selective inhibitors of Rab geranylgeranyl transferase (RabGGTase, RGGT), an enzyme implicated in several diseases including ovarian, breast and skin cancer. Here we present the synthesis and biological characterization of an extended set of this class of compounds, including lipophilic derivatives of the known RGGT inhibitors. From this new panel of PCs, we have identified an inhibitor of RGGT that is

    The reaction of chloro, chloromethyl and chlorophenyl carbenoids with ketene alkylsilylacetals has been studied. Excellent yields of cyclopropanation were observed and the unstable chlorocyclopropanone acetals formed were thermally rearranged in high yield into α-substituted α,β-ethylenic esters. This new method for the synthesis of unsaturated esters appeared complementary of the known-ones.
