摘要
阐述了一种SGLT1/2抑制剂1,6-脱水-1-C-[4-氯-3-[(4-三氟甲氧基苯基)甲基]苯基]-5-C-(羟甲基)-β-L-艾杜吡喃糖(1)的合成方法。该方法以[(3S,4S,5R,6S)-3,4,5-三苄氧基-6-[4-氯-3-[[4-(三氟甲氧基)苯基]甲基]苯基]-2-羟甲基-6-甲氧基-四氢吡喃-2-基]甲醇(2)为原料,经过成环反应得到[(1R,2S,3S,4R,5R)-2,3,4-三苄氧基-5-[4-氯-3-[[4-(三氟甲氧基)苯基]甲基]苯基]-6,8-二氧杂双环并[3.2.1]辛烷-1-基]甲醇(3),化合物3经过氢化脱苄得到化合物(1)。该工艺路线操作简单,可操作性强,副反应少,反应收率高,适合工业化生产。
A SGLT1/2inhibitor(1R,2S,3S,4R,5R)-5-(4-chloro-3-(4-(trifluoromethoxy)benzyl)phenyl)-1-(hydroxymethyl)-6,8-dioxabicyclo[3.2.1]octane-2,3,4-triol(1)was synthesized using((3S,4S,5R,6S)-3,4,5-tris(benzyloxy)-6-(4-chloro-3-(4-(trifluoromethoxy)benzyl)phenyl)-6-methoxytetrahydro-2 H-pyrane-2,2-diyl)dimethanol(2)as the starting material,which is reacted to give((1R,2S,3S,4R,5R)-2,3,4-tris(benzyloxy)-5-(4-chloro-3-(4-(trifluoromethoxy)benzyl)phenyl)-6,8-dioxybicyclo[3.2.1]octan-1-yl)methanol(3).The compound 1was obtained by debenzylation of compound3.The synthetic process is suitable for industrial production with simple operation and high reaction yield.
