Damascenone has been shown to undergo reaction with common wine components. Following the action of acid and heat alone, two bicyclic compounds, 4,9,9-trimethyl-8-methylenebicyclo[3.3.1]non-6-en-2-one (2) and 4,4,9-trimethyl-8-methylenebicyclo[3.3.1] non-6-en-2-one (3), were isolated. However, this conversion takes place only very slowly, if at all, under milder conditions (45 degrees C). When treated
已证明大马烯酮会与常见的葡萄酒成分发生反应。仅在酸和热作用下,两个双环化合物即4,9,9-三甲基-8-亚甲基双环[3.3.1] non-6-en-2-one(2)和4,4,9-三甲基-分离出8-亚甲基双环[3.3.1]非6-en-2-one(3)。但是,这种转换仅在非常温和的条件下(45摄氏度)才非常缓慢(如果有的话)进行。当在pH 3.0和5.5的条件下用各种亲核试剂处理时,除了在pH 5.5时添加半胱氨酸和2-巯基乙醇(约40%和约30%)外,缓冲水溶液中的大马烯酮浓度会少量降低(10-20%),分别)和SO2(pH 3.0时> 90%; pH 5.5时100%)。制备了来自该最后组合的加合物,其显示为大马烯酮的C9磺酸衍生物。
