A process involving the hydroformylation/O-acylation of propenylbenzenes with a phenolic group is described for eugenol, isoeugenol, chavicol, propenyl guaethol, 2-allylphenol, and 2-allyl-6-methylphenol. The reactions occur in parallel, under the same reaction conditions in anisole, a solvent with an impressive sustainability rank comparable to those of ethanol and water. The products contain formyl
描述了涉及丁香酚、异丁香酚、茶维酚、丙烯基愈创木酚、2-烯丙基苯酚和2-烯丙基-6-甲基苯酚的丙烯基苯与酚基的加氢甲酰化/O-酰化的方法。这些反应在相同的反应条件下在苯甲醚中并行发生,苯甲醚是一种具有令人印象深刻的可持续性等级的溶剂,可与乙醇和水相媲美。这些产品含有甲酰基和乙酰氧基部分,这两种基团都是香精香料工业中已建立的嗅觉基团,并且具有作为具有较少致敏特性的新香料成分的潜力。据我们所知,这是第一次描述涉及加氢甲酰化结合远程站点进一步功能化的单锅法。
