Abstract
本发明涉及一种用于由包含C1‑3含氧化合物(例如甲醛、乙醇醛、乙二醛、丙酮醛或丙酮醇)的组合物制备C4含氧化合物(例如苏糖、赤藓糖或赤藓酮糖)的方法,其中该方法在结晶微孔材料的存在下进行,该结晶微孔材料具有选自八元环孔结构和十元环孔结构的环孔结构。
Description
背景:
C4含氧化合物,例如C4糖(例如赤藓糖、苏糖和赤藓酮糖)的选择性和高收率制备对于其在化学工业中用于制备例如以下物质的用途能够被证明是有价值的:C4多元醇;乙烯基乙醇酸甲酯或由其获得的产物;2-羟基-4-甲氧基丁酸或其盐或酯(如2-羟基-4-甲氧基丁酸甲酯)。
制备C4含氧化合物的已知方法包括乙醇醛的醛醇自缩合。已经观察到,醛醇缩合对于C4含氧化合物的制备不是选择性的;随着C4产物继续反应以形成具有更大碳原子数的含氧化合物时,观察到产物的混合物。为了控制反应对于C4含氧化合物的选择性,需要形成C4含氧化合物和硅酸盐或硼酸盐的复合物,或使用C4含氧化物选择性催化剂。
硅酸盐复合物用于选择性形成C4含氧化合物的实例包括在含水硅酸钠存在下的乙醇醛的醇醛缩合;Science(2010)327,pp 984-986。在反应期间,形成硅酸盐-C4-糖复合物,从而控制反应的选择性。另一个实例包括乙醇醛在硼酸盐缓冲液存在下的缩合。获得高收率(86%)的C4含氧化合物(C4糖);J.Am.Chem.Soc.(2011)133,pp 9457-9468。
C4-含氧化合物选择性催化剂的实例包括在同手性二肽催化剂的存在下通过乙醇醛的醛醇缩合来制备C4含氧化合物。C4含氧化合物产物的收率高达63%;PNAS(2006)103,pp12712-12717。或者,可以使用锌-脯氨酸催化剂。C4-糖产物的总收率为约51%。C6-糖以约30%的收率形成;Org.Biomol.Chem.(2005)3,pp 1850-1855。
来自乙醇醛的C4含氧化合物的替代制备包括所提出的在2-羟基-4-甲氧基-丁酸酯(C4)和乙烯基乙醇酸甲酯(C4)的制备中的四糖瞬时中间体。反应在沸石型催化剂的存在下进行。该沸石型材料是Sn-BEA,一种十二元环孔结构;Green Chemistry(2012)14,pp702-706。
替代的沸石型材料,例如十元环孔结构化沸石型(例如Sn-MFI或Ti-MFI),可用于使C2含氧化合物异构化。这种沸石型材料已用于使乙二醛异构化为乙醇酸。乙醇酸的收率为约90%;Green Chemistry(2014)16,pp1176-1186。
本发明的一个目的是提供一种用于由包含C1-3含氧化合物的组合物制备C4含氧化合物的方法,其中该方法对于C4含氧化合物的生产是选择性的,并且产物以高收率获得。
发明内容
现已发现,在包含小孔或中孔结构的结晶微孔材料的存在下,可以将乙醇醛选择性地转化为C4含氧化合物。该反应以高收率进行。另外,可在其他化合物存在下进行反应,以选择性地形成期望的C4含氧化合物。

通过本发明的方法制备的C4含氧化合物可以被转化为乙烯基乙醇酸甲酯和2-羟基-4-甲氧基丁酸或其盐或酯。Science(2010)328,pp 602–605和Green Chemistry(2012)14,pp 702-706公开了合适的合成方法。另外,可以在相同的条件下或在如ACS Catal.,2013,3(8),pp 1786-1800中描述的条件下由C4含氧化合物制备α-羟基-γ-丁内酯。

在本发明的第二个实施方案中,蛋氨酸α-羟基类似物选自2-羟基-4-(甲硫基)丁酸甲酯、2-羟基-4-(甲硫基)丁酸乙酯、2-羟基-4-(甲硫基)丁酸丙酯、2-羟基-4-(甲硫基)丁酸丁酯、2-羟基-4-(甲硫基)丁酸异丙酯、2-羟基-4-(甲硫基)丁酸戊酯、2-羟基-4-(甲硫基)丁酸己酯、2-羟基-4-(甲硫基)丁酸庚酯、2-羟基-4-(甲硫基)丁酸辛酯和2-羟基-4-(甲硫基)丁酸2-乙基己酯。
通过本发明的方法制备的C4含氧化合物可以被转化为丁二醇,如ChemSusChem(2012)5,pp 1991-1999中所述。
用于由C1-3含氧化合物制备C4含氧化合物的方法也可以与由C4含氧化合物形成C4多元醇的氢化反应同时进行。因此,反应可以在一个步骤中进行,即“一锅”反应。“一步”或“一锅”反应是指用于将乙醇醛转化为C4含氧化合物的结晶微孔材料和用于使C4含氧化合物氢化的金属催化剂同时存在于反应容器中。当氢化产物(C4多元醇)存在时,反应被淬灭。
C4多元醇是指包含链长为四个碳原子的化合物并且每个碳原子与醇(OH)官能团键合的C4含氧化合物。C4多元醇也可以称为四碳糖醇,并且具有分子式C4H10O4。C4多元醇是选自赤藓糖醇和苏糖醇的一种或多种化合物。赤藓糖醇和苏糖醇包括所有的立体异构体,例如D-和L-苏糖醇。赤藓糖醇可用作食品、甜味剂和用于丁二醇的制备。ChemSusChem(2012)5,pp1991-1999说明了由赤藓糖醇制备丁二醇。

根据EP 2184270B1中所述的方法制备Sn-BEA。
Sn-LTA:
可以从LTA沸石(Sigma-Aldrich,Molecular sieves,)制备具有(Si/Sn=125)的125Sn-LTA。将LTA在450℃下在蒸汽下处理6小时,用1M的HCl在100℃下酸洗16小时,并用充足的水洗涤。将固体在120℃下干燥16小时,用SnCl2水溶液浸渍并在550℃下煅烧(2℃/min)6小时。
