    Amine-Catalyzed Direct Aldol Addition
    摘要:
    An efficient organo-catalytic, highly syn-stereoselective method for aldol additions between enolizable aldehydes and hydroxyacetone as well as dihydroxyacetone is disclosed. Reactions proceed in the presence of tertiary amines at room temperature. The aldol adducts can be obtained in good to high yields and with high degrees of syn-diastereoselectivity. This new aldol reaction provides an operationally simple protocol for the stereocontrolled synthesis of carbohydrates

    three-step mechanism for the formation and growth of carbonaceous spheres by hydrothermal carbonization of saccharides using sucrose as a precursor material. Carbonaceous spheres with small diameters and narrow size distribution were synthesized via a rapid heating route, and a notable phenomenon of a sudden drop in the mean diameter of the carbonaceous spheres at low concentration with the extension of
    我们报告了一个新的三步机制,通过使用蔗糖作为前体材料对糖类进行水热碳化来形成和生长碳质球。通过快速加热途径合成了小直径且尺寸分布窄的碳质球,观察到明显的现象,即随着时间的延长,在低浓度下碳质球的平均直径突然下降。通过场发射扫描电子显微镜(FESEM),傅立叶变换红外光谱(FT-IR)和溶液13分析了碳球的形貌,化学结构和残留溶液的化学组成。C核磁共振(NMR)。基于这些结果,清楚地揭示了固体产物的演变。地层包含两个阶段,归因于果糖被所产生的酸(甲酸)自动催化而导致的一次颗粒过饱和,导致在第二个阶段中出现大量碳球,这解释了平均直径的突然下降。
