The invention provides a synthetic method of (purin-6-yl)amino acids which are useful as medicaments of anticancer, anti-virus agents and so on or their intermediates. Methyl (R, S)-3-[4-(9-benzylpurin-6-yl) phenyl]-2-[ (t-butoxycarbonyl) amino] propanoate is produced by making 9-benzyl-6-iodopurine react with methyl (R, S)-2-[ (t-butoxycarbonyl) amino]-3-[4-(trimethylstananyl) phenyl] propionate in the presence of Pd2dba3, triphenylarsine and copper iodide.
Viscosity-Induced Emission of 5-(Diarylmethylene)imidazolone with Extended Conjugation <i>via</i> Attachment of <i>N</i>-Methylpyrrole at the 2-Position
We have developed a series of 2-monoaryl-5-diarylmethylene analogs of the green fluorescent protein chromophore to study their viscosity-induced emission (VIE) properties. The analogs were synthesized by a condensation with methyl imidate and N-(diarylmethylene)glycinate. Among the analogs, the N-methylpyrrol-2-yl-substituted analog 1h induced the most remarkable VIE behavior in triglyceride and lipid
我们开发了一系列绿色荧光蛋白发色团的 2-单芳基-5-二芳基亚甲基类似物,以研究它们的粘度诱导发射 (VIE) 特性。通过与亚氨酸甲酯和N- (二芳基亚甲基)甘氨酸酯缩合合成类似物。在这些类似物中, N-甲基吡咯-2-基取代的类似物1h在甘油三酯和脂质双层中诱导了最显着的 VIE 行为,这可能是由于吡咯环的高 π 电子丰富特性。咪唑啉酮类似物中的吡咯取代基有望成为引入 VIE 行为的通用模板。 全尺寸图像
