A range of hitherto unexplored biomass-derived chemicals have been evaluated as new sustainable solvents for a large variety of CO2 -based carboxylation reactions. Known biomass-derived solvents (biosolvents) are also included in the study and the results are compared with commonly used solvents for the reactions. Biosolvents can be efficiently applied in a variety of carboxylation reactions, such as Cu-catalyzed carboxylation of organoboranes and organoboronates, metal-catalyzed hydrocarboxylation, borocarboxylation, and other related reactions. For many of these reactions, the use of biosolvents provides comparable or better yields than the commonly used solvents. The best biosolvents identified are the so far unexplored candidates isosorbide dimethyl ether, acetaldehyde diethyl acetal, rose oxide, and eucalyptol, alongside the known biosolvent 2-methyltetrahydrofuran. This strategy was used for the synthesis of the commercial drugs Fenoprofen and Flurbiprofen.

新的生物质衍生溶剂的探索：在羧化反应中的应用。

迄今为止，尚未开发的一系列生物质衍生的化学品已被评估为各种基于CO2的羧化反应的新型可持续溶剂。研究中还包括已知的生物质衍生溶剂（biosolvents），并将结果与​​反应中常用的溶剂进行比较。生物溶剂可以有效地应用于各种羧化反应中，例如铜催化的有机硼烷和有机硼酸酯的羧化反应，金属催化的加氢羧化反应，硼化羧化反应以及其他相关反应。对于许多这些反应，使用生物溶剂可提供比常用溶剂可比或更高的产率。迄今为止，确定的最佳生物溶剂是尚未开发的候选异山梨醇二甲醚，乙醛二乙基乙缩醛，氧化玫瑰和桉油精，以及已知的生物溶剂2-甲基四氢呋喃。该策略用于合成商业药物非诺洛芬和氟比洛芬。
