  • Metal substituted diazo esters as substrates for cross coupling reactions

    nucleophiles. The base-promoted reaction of ethyl 4-azido-2-diazo-3-oxo-butanoate with both acetaldehyde and benzaldehyde proceeded in high yield to produce mixed aldol products. The use of an equivalent amount of DABCO was found to be the best way to promote the reaction. The diastereoselectivity exhibited in the reaction is low and characteristic of condensations of α-substituted ketones with substituents
    (三烷基锡烷基)重氮乙酸乙酯已被用作Stille反应的底物。钯(0)催化的交叉偶联可与芳基碘化物很好地起作用,而与酰基或芳基氯化物不能很好地起作用。比斯-[[乙氧基羰基-重氮甲基]-汞显示出对溴乙酰溴的高反应活性,以优异的产率提供了4-溴-2-重氮-3-氧代-丁酸乙酯。该化合物用于与各种亲核试剂的取代反应。4-叠氮基-2-重氮-3-氧代丁酸乙酯与乙醛和苯甲醛的碱促进反应以高收率进行,以生产混合的醛醇产物。发现使用等量的DABCO是促进反应的最佳方法。反应中显示的非对映选择性低,并且α-取代的酮与在α-位的烷基以外的取代基缩合的特征。对于2-重氮-3-氧代-4-苯基丁酸乙酯与乙醛和苯甲醛的反应也发现了类似的结果。

    A series of pyridine-2-carboxylic acid derivatives were synthesized according to the leads from the screening, and potent inhibitors have been obtained by structural modification. They have shown submicromolar inhibition of the enzymes (for example, for 9n, IC50 = 130 nM for EcMetAP1 and IC50 = 380 nM for ScMetAP1). They represent small-molecule MetAP inhibitors with novel structures different from alkylating fumagillin derivatives and peptidic bestatin-based MetAP inhibitor.
