Abstract: 2-L-Tyrosine-2-deoxy-D-glucose was synthesized using D-fructose and L-tyrosine,the structure of the product was characterized by IR, 1H NMR, 13C NMRand HR-MS spectra.The thermal decomposition of 2-L-tyrosine-2-deoxy-D-glucose was investigated by Thermogravimetry-Differential Thermal Analysis (TG-DTA) and online pyrolysis gas chromatography-mass spectroscopy (Py-GC/MS).The results showed that:1) Synthetic product was the target compound;2) The pyrolysis temperature of the target compound was 153.01  ℃,the total weight loss of the target compound reached 86% when the temperature was 600  ℃;3) The number of cleavage products including heterocycles,ketones,carboxylic acids,aldehydes and alcohols,increased with the rise of pyrolysis temperature and featured sweet,burnt-sweet,baked,nutty,floral and creamy flavors.

Key words: 2-L-tyrosine-2-deoxy-D-glucose, synthesis;pyrolysis, GC/MS
