restricts its application to reactions that require non-polar solvents. Furthermore, pursuing solvent-free conditions, even without liquid substrates, might result in similar conversion rates with reduced catalyst loading. These findings highlight the potential of exploring solvent-free conditions when enantioselectivity is not of concern. Based on the results, solvent-free conditions and bio-based solvents
在这项研究中,我们深入研究了使用绿色溶剂或无溶剂条件下进行的各种反应,利用氢键有机催化来推进化学合成中更可持续的实践。结果表明,环戊基甲基醚有可能取代己烷和甲苯等非极性有机溶剂,并具有相当的对映选择性和产率。液化或超临界CO 2的非极性性质限制了其在需要非极性溶剂的反应中的应用。此外,追求无溶剂条件,即使没有液体底物,也可能在减少催化剂负载的情况下产生相似的转化率。这些发现凸显了在不关心对映选择性时探索无溶剂条件的潜力。根据结果,无溶剂条件和生物基溶剂可以作为传统有机溶剂的可行替代品,而不会影响性能。预计这将影响化学家在该领域的方法开发中实现反应优化的方式,从而促进更广泛地采用环保方法。
