摘要: 以β-碳苷酮为原料合成了4个新的β-碳苷酮的笼状缩酮衍生物,采用1H NMR、13C NMR、 DEPT及二维谱1H-1H COSY、HSQC、HMBC和高分辨质谱(HRMS)对其结构进行了研究和确证,并对它们的1H、13C NMR全谱给予了准确归属.

Abstract: Caged intramolecular ketals of β-C-glycosidic ketones were prepared from β-C-glycosidic ketones. The structures of these C-glycosidic derivatives were evaluated with 1D and 2D NMR spectroscopy (i.e., 1H NMR, 13C NMR, DEPT-135, 1H-1H COSY, HSQC and HMBC) and high resolution mass spectra. 1H and 13C NMR chemical shifts of these compounds were assigned.

Key words: NMR, assignments, β-C-glycosidic ketone, caged intramolecular ketals
