Org. Lett. 2010, 12, 1748-1751
1,13-Dimethoxychromenoxanthenium – a key intermediate in the synthesis of the classical trioxatriangulenium cation – was isolated and characterized for the first time. This helicene was resolved through a CSP-HPLC procedure; chemical and configurational stabilities being determined and compared.
