    摘要:
    固定在Eupergit C珠上的青霉素酰化酶催化在水/ CH 3 CN 10:1中在pH 7.5和23°C下水解一系列邻苯甲醇的邻苯乙酸酯。在与青霉素(1)骨架结构相关的2,2-二甲基-1,3-二氧戊环-4-甲醇中观察到最高的对映选择性。对这种基本结构的微小修饰不会改变酶的可接受性,但会显着降低水解的对映选择性,就像使用苯作为溶剂和与琼脂糖结合的酶一样。

    Stereoselective Formal Total Synthesis of (+)-Methynolide
    摘要:
    A highly stereoselective and convergent formal total synthesis of (+)-methynolide is described. The salient features of this synthesis have been the construction of the C1-C7 and C8-C11fragments via a desymmetrization approach, Sharpless asymmetric epoxidation of an allyl alcohol, respectively, and linkage of both the fragments by Nozaki-Hiyama-Kishi reaction.

  • Esterification of Carboxylic Acids by Alcohols with 2-Chloro-1,3,5-trinitrobenzene as Condensing Agent
    作者:Seiji Takimoto、Junji Inanaga、Tsutomu Katsuki、Masaru Yamaguchi
    DOI:10.1246/bcsj.54.1470
    日期:1981.5
    When mixtures of carboxylic acids or their sodium salts and alcohols were treated with 2-chloro-1,3,5-trinitrobenzene in the presence of pyridine under mild conditions, the corresponding carboxylic esters were formed. The yields and the rates of the ester formation depended on the types of the acids and the alcohols used.

    Novel sources of antibiotics are required to address the serious problem of antibiotic resistance. Telithromycin (2) is a third-generation macrolide antibiotic prepared from erythromycin (1) and used clinically since 2004. Herein we report the details of our efforts that ultimately led to the total synthesis of (-)-4,8,10-tridesmethyl telithromycin (3) wherein methyl groups have been replaced with hydrogens. The synthesis of desmethyl macrolides has emerged as a novel strategy for preparing bioactive antibiotics.

  • Substrate specificity and enantioselectivity of penicillinacylase catalyzed hydrolysis of phenacetyl esters of synthetically useful carbinols
    作者:Claudio Fuganti、Piero Grasselli、Stefano Servi、Ameriga Lazzarini、Paolo Casati

    日期:1988.1
    Penicillinacylase from , immoblized on Eupergit C beads catalyzes the hydrolysis in water/CH3CN 10:1, at pH 7.5 and 23° C, of a set of O-phenylacetate esters of primary carbinols. The highest enantioselectivity is observed in the case of the 2,2-dimethyl-1,3-dioxolane-4-methanols structurally related to the penicillin (1) framework. Minor modifications of this basic structure are not altering the acceptability
