    2) lignin‐SO3Cu(OTf), and 3) lignin‐IL@NH2 (IL=ionic liquid). These solid materials were then examined in many organic transformations. It was finally found that, compared with its homogeneous counterpart as well as some other solid catalysts that are prepared by using different supports with the same metal or catalytically active species, the lignin‐supported catalysts showed better performance in these reactions

  • Gluconic acid aqueous solution: a task-specific bio-based solvent for ring-opening reactions of dihydropyrans
    作者:Jie Yang、Binghua Zhou、Minghao Li、Yanlong Gu
    DOI:10.1016/j.tet.2012.11.076
    日期:2013.1
    Gluconic acid aqueous solution (GAAS) that is a largely available bio-based chemical was proved to be an effective task-specific medium for ring-opening reactions of dihydropyrans. In the presence of nucleophiles, such as indoles, 1,3-cyclohexanediones, N,N-dimethylaniline, N-methylaniline, 2-naphthol, and resorcin, a series of 2-substituted 1, 3-dicarbonyl compounds were synthesized in good to excellent yields. The first example of ring-opening of oxa-Pictet-Spengler product with nucleophiles was also described. These results not only demonstrate the feasibility of using GAAS as a sustainable solvent, but also offer an effective way for the ring-opening reactions of dihydropyrans with nucleophiles. Because these reactions proceeded with excellent atom-economy in a sustainable bio-based solvent, the present method was thus characterized by many properties of green chemistry, such as green solvent, atom-economy, and utilization of bio-based chemicals.
