1,13-Dimethoxychromenoxanthenium, a key intermediate in the synthesis of the classical trioxatriangulenium cation, was isolated and characterized for the first time. This [4]helicene was resolved through a CSP-HPLC procedure, with chemical and configurational stabilities being determined and compared.
首次分离并表征了1,13-二甲氧基chromenoxanananthan,这是合成经典三氧杂triangulenium阳离子的关键中间体。通过[C
SP-HPLC]方法分离[4]螺旋烯,并确定和比较其
