Six new dimeric 2-(2-phenylethyl)chromones from artificial agarwood of Aquilaria sinensis

Six new dimeric 2-(2-phenylethyl)chromones (1–6) were isolated from the EtOAc extract of artificial agarwood originating from Aquilaria sinensis (Lour.) Glig. Their structures were unambiguously elucidated by spectroscopic techniques (UV, IR, 1D and 2D NMR), and HRESIMS analysis, as well as by compa...

More Information
Summary:Six new dimeric 2-(2-phenylethyl)chromones (1–6) were isolated from the EtOAc extract of artificial agarwood originating from Aquilaria sinensis (Lour.) Glig. Their structures were unambiguously elucidated by spectroscopic techniques (UV, IR, 1D and 2D NMR), and HRESIMS analysis, as well as by comparison with the literature. The absolute configurations were determined by ECD spectra. [Display omitted]
