摘要
为了提高糠醇-β-D-葡萄糖苷的合成产率,对其合成条件进行了优化,并对糠醇-β-D-葡萄糖苷的热裂解产物及卷烟主流烟气粒相中糠醇的转移率进行了分析。结果表明:①糠醇与乙酰溴-α-D-葡萄糖在以硅胶担载的Ag_(2)CO_(3)为催化剂、NaOH固体为缚酸剂的条件下进行糖苷化反应,得到糠醇-2,3,4,6-四-O-乙酰基-β-D-葡萄糖苷,产率为45.9%;糠醇-2,3,4,6-四-O-乙酰基-β-D-葡萄糖苷脱去乙酰基,得到糠醇-β-D-葡萄糖苷,产率为90.1%。合成产物的结构通过1HNMR、13CNMR、FTIR和HRMS技术得到确证。②在不同温度下,糠醇-β-D-葡萄糖苷的主要裂解产物均为糠醇。③糠醇-β-D-葡萄糖苷在卷烟燃吸时能够释放出糠醇,主流烟气粒相中糠醇的转移率为0.68%。
To improve the synthesis yield of furfuryl alcohol-β-D-glucoside in smoke,synthesis conditions and pyrolysis products were investigated and the transfer rate of furfuryl alcohol to the particulate phase of mainstream cigarette smoke was measured.The results showed that:1)Furfuryl alcohol and acetyl bromide-α-D-glucose underwent glycosylation reaction under the catalysis of Ag_(2)CO_(3)supported on silica gel and NaOH solid as acid binder to obtain furfuryl alcohol-2,3,4,6-tetra-O-acetyl-β-D-glucoside.The optimized yield of furfuryl alcohol-2,3,4,6-tetra-O-acetyl-β-D-glucoside was 45.9%.The intermediate furfuryl alcohol-2,3,4,6-tetra-O-acetyl-β-D-glucoside was deacetylated to obtain furfuryl alcohol-β-D-glucoside with a yield of 90.1%.The structures of the intermediates and the final products were confirmed by 1H NMR,13C NMR,FTIR and HRMS.2)At different temperatures,the main cleavage product of furfuryl alcohol-β-D-glucoside was furfuryl alcohol.3)Furfuryl alcohol-β-D-glucoside released furfuryl alcohol during cigarette smoking,and the transfer rate of furfuryl alcohol to the particulate phase of mainstream cigarette smoke was 0.68%.
