  • Asymmetric synthesis of cis-2,4-disubstituted azetidin-3-ones from metal carbene chemistry
    作者:Antonio Carlos B. Burtoloso、Carlos Roque D. Correia
    DOI:10.1016/j.jorganchem.2005.07.016
    日期:2005.12
    Several chiral cis-2,4-disubstituted azetidin-3-ones were prepared as single diastereoisomers from N-protected amino acids, employing a highly stereoselective copper carbenoid N–H insertion reaction of diazoketones. These azetidin-3-ones were then converted into fully substituted azetidines in a few steps in good to high yields.
    利用重氮酮的高度立体选择性的铜类碳氢化合物N-H插入反应,由N-保护的氨基酸制备了几种手性顺式-2,4-二取代的氮杂环丁烷-3-酮,作为单一的非对映异构体。然后将这些氮杂环丁烷-3-酮以良好至高收率的几步转化为完全取代的氮杂环丁烷。

    Analysis of the formation and repair of structurally modified DNA is of particular interest in the study of carcinogenesis, cancer therapy and aging. The quantification of specific DNA lesions by sensitive immunoanalytical methods requires radiotracers with high specific activity. We describe the synthesis of 3H-labelled adenine-, cytosine-, guanine- and thymine-alkyl derivatives by nucleophilic N- and O-alkylation using alkyl halides and diazoalkanes: 3-alkyl-[8-3H]adenine (Alkyl = Me, Et, n-Bu); O6-alkyl-deoxy[1′,2′-3H]guanosine (Alkyl = Me, Et, i-Pro, n-Bu); O6-ethyl-deoxyguanosine-5′-triphosphate ([2-3H-Ethyl]; [8-3H]); O6-alkyl-9-hydroxyhexyl-[8-3H] guanine (Alkyl=Me, Et); 7-ethyl-[8,5′-3H]guanosine-3′,5′-cyclic-phosphate; O2-andO4-alkyl-[methyl, 1′,2′-3H]thymidine (Alkyl=Me, Et); the conversion of 3H-labelled thymidine to the corresponding 5-methylcytidine; the synthesis of three different 8-oxo-guanine tracers; and the generation of thymidine glycol (5,6-dihydroxy-5,6-dihydro-[methyl-3H]thymidine) from thymidine. All radiotracers were sucessfully employed in competitive radioimmunoassays for the quantification of defined DNA alkylation products in DNA repair analyses. Copyright © 2003 John Wiley & Sons, Ltd.

    The eighteen new μ-alkylidene ruthenium complexes 5a–r and 5t are very easily and cleanly obtained along the diazoalkane or the hydrazone routes that involve treatment of the dinuclear, metal-metal doubly bonded precursor compound [(η5-C5H5)Ru(μ-NO)]2 (3) either with the diazoalkanes oxidizing agent (e.g., MnO2), with the respective hydrazones. Similarly, sulfur dioxide adds cleanly to the RuRu double
    十八新μ亚烷基钌配合图5a-R和5吨非常容易且干净地沿着重氮烷或涉及治疗双核,金属-金属双键前体化合物的腙途径获得[(η 5 -C 5 H ^ 5) Ru(μ-NO)] 2(3)或重氮烷烃氧化剂(例如MnO 2)和相应的。类似地,二氧化硫干净地增加的RURU双键3,由此得到配合物(μ-SO 2)[(η 5 -C 5 H ^ 5)的Ru(NO)] 2(5S)。不管卡宾桥配体的性质如何,与它们的铁类似物相比,双金属环丙烷仅表现出末端亚硝酰基配体。对于显示出不对称取代的卡宾桥的衍生物,观察到具有占主导地位的反式异构体的顺式/反式异构现象。

    A superior method for generation of diazomethane and several other gaseous diazoalkanes has been provided by alkali treatment of N-[(N-nitrosoalkylamino) methyl]-carbamates, especially their isopropyl esters, which react smoothly in high yields (81-82% for diazomethane).
