A polyoxygenated cyclohexane derivative, (-)-quebrachitol [(1R, 3R, 4S, 6S)-2-methoxy cyclohexane-1,3,4,5,6-pentol] (1) was isolated from the stems of Acer chiangdaoense. Additionally, this is the first report of phytochemical from this plant. The structure was recognised by spectral methods, principally 2D NMR spectroscopic techniques, which complicated pooled applications of COSY, HMQC and HMBC. The relative configurations of the molecular structure of 1 were similarly confirmed by single crystal X-ray diffraction.
