Xylariaone, A New Cyclohexanone from Xylaria sp. 12F0758

A new cyclohexan-1-one, named xylariaone (1), was isolated from the fungal strain Xylaria sp. 12F0758. Its structure was elucidated by spectroscopic analyses, including 1D and 2D NMR experiments, and by high-resolution fast atom boardment (HR-FAB-MS) mass spectrometry. 10.1007/s10600-022-03811-w Link to publiion in Scopus …

    14/3/2020· Since there are multiple peaks, the "Hd"s are chemically distinct. That is also observed when we use do the NMR analysis with higher resolution (See the second spectrum below). Indeed, I have 1H NMR results with slightly better resolution. For "Hc" and "Hd"s, we can indeed resolve 4 peaks corresponding to signals at ~1.9, ~1.8, ~1.7 ~1.3ppm.

    Cyclohexanone - Wikipedia

    Cyclohexanone is the organic compound with the formula (CH 2) 5 CO. The molecule consists of six-carbon cyclic molecule with a ketone functional group. This colorless oily liquid [3] has an odor reminiscent of acetone. Over time, samples of cyclohexanone assume a pale yellow color. [10]
