日期:——
oxidation of α-bisabolol, a bio-renewable substrate with strong therapeutic potential available from various essential oils, has been developed. The reaction gives three main products arising from the oxidation of the sterically encumbered trisubstituted double bonds of the substrate, either endocyclic or exocyclic or both. Novel poly-functionalized sesquiterpenoids obtained with high combined selectivity
钯/ p已经开发了对苯二酚催化的α-bisabolol的有氧氧化,α-bisabolol是一种可从各种精油中获得的具有强大治疗潜力的生物可再生底物。该反应产生三种主要产物,这是由于底物的空间受阻的三取代双键的氧化而产生的,是环内的或环外的或两者兼而有之。由α-bisabolol的氧化而获得的具有高组合选择性的新型多官能倍半萜可能潜在地用作合成香料,化妆品和药物的成分。该系统在超大气氧压下不存在辅助氧化还原活性助催化剂的情况下,可促进有效的双氧耦合催化转化。或者,
