Abstract
本发明公开了一种涉及Heck反应新的制备白藜芦醇和Piceatannol和其酯的方法。本发明还公开了此方法中的新的中间体。
Description
本发明涉及一种新的制备苯乙烯基衍生物的方法。更具体的是,本发明涉及一种新的制备白藜芦醇和Piceatannol和其酯的方法。
白藜芦醇(Resveratrol)存在于自然界中,系统名为3,4’,5-三羟基二苯乙烯,它是一种已知化合物,由于它的生物性质(参见例如国际专利申请WO 01/60774),所以备受关注。Picetannol也是一种已知化合物,系统名为3,3’,4,5’-四羟基二苯乙烯。
除其它文献以外,WO 01/60774和Tetrahedron Letter 43(2002)597-598中已经公开了白藜芦醇的制备方法。后一参考文献描述了如下方法,其中,通过多步反应由3,5-二羟基苯甲醛开始,包括3,5-二羟基苯乙烯与4-乙酰氧基-碘化苯的Heck反应制备白藜芦醇,产率为70%。本发明的方法使用更易得到的原料且进行的反应步骤更少,产率更高,因此为制备自藜芦醇和Picetannol和其衍生物(例如酯),提供了一种技术上更吸引人的方法。
一方面,本发明涉及一种制备白藜芦醇和Piceatannol和其酯的方法,该方法包括将式I化合物
与式II的化合物反应
其中,Z和Z1分别为被保护的羟基;Z2是氢或Z1;且A和B其中之一是乙烯基,另一为氯或溴;
以得到式III化合物
其中Z和Z1如上定义,R1是氢或Z1;
由式III的化合物裂解羟基保护基得到白藜芦醇或Piceatannol,如果希望的话,将所得到的白藜芦醇或Piceatannol转化成酯,如果还希望的话,将(E)-白藜芦醇或其酯或者(E)-Piceatannol或其酯异构化以得到相应的(Z)-异构体。
此处使用的术语“白藜芦醇”和“Piceatannol”指(E)和(Z)异构体和其混合物。在优选的方面,本发明涉及(E)异构体的制备方法。更优选的是,本发明涉及(E)白藜芦醇的制备方法。
被保护的羟基Z和Z1上的保护基团可以是任何可解离的保护基团。这种保护基团实例是吸电子基团,例如酰基,比如直链的或分枝的烷酰基,具体的是乙酰基,或芳酰基,例如苯甲酰;碳酸酯基,比如甲氧基羰基、乙氧基羰基和苄氧基羰基;氨基甲酸酯基,例如甲基氨基甲酰基;和磺酸酯,例如甲苯磺酸酯和甲烷磺酸酯。保护基团Z和Z1另外的实例是非吸电子基团,比如缩醛基,例如甲氧基亚甲基、乙氧基亚乙基、甲氧基甲基、苄氧基甲基、四羟基吡喃基、1-乙氧基乙基和1-甲氧基-1-甲基乙基,或甲硅烷醚,比如三甲基甲硅烷基、三异丙基甲硅烷基和叔丁基二甲基甲硅烷基。引入和解离这些保护基团的技术是本领域所已知的,参见例如T.W.Greene和P.G.M.Wuts(des.)Protective Group in Organic Synthesis,第三版,John Wiley 1999 246-287和其中引用的文献。
式I化合物与式II化合物的反应可以在本身已知的Heck反应条件下实施。合适的是,使用约等摩尔量的式I化合物和式II化合物。作为反应溶剂,可以使用任意惰性有机溶剂,这种溶剂的实例是有机溶剂,例如烃,比如甲苯;醚,比如二氧杂环己烷;腈,比如乙腈;酮,比如丙酮和酰胺,比如二甲基甲酰胺或N-甲基吡咯烷酮。而且,该反应适合在碱的存在下实施,该碱可以是无机碱,例如碳酸盐和碳酸氢盐,比如碳酸钠和碳酸氢钠、叔磷酸盐,例如K3PO4,或可以是有机碱,例如胺,比如三乙基胺或二异丙基乙基胺或碱金属的乙酸盐,比如乙酸钠。分别根据反应物I和反应物II以至少等摩尔量使用碱。而且,根据Heck反应的通用条件,可以加入催化剂,该催化剂包括钯源,比如乙酸钯或Pd(dba)2和稳定配合剂,例如膦,比如三邻甲苯基膦,或铵盐,例如四丁基氯化铵。而且,已证明钯催化剂和环状钯(palladacycle),例如肟衍生的钯配合物或反式-二(μ-乙酸)-二[(o-甲苯膦基)苄基]钯II(参见Advanced Synthesis and Catalysis344(2002),172-183和Journal of Organometallic Chemistry 576(1999),23-41)是适宜的钯源。
该反应适于在常压或高压下、在高温下(例如不高于适当压力下的使用溶剂的沸点温度)、且在惰性气氛(例如氩气)中实施。
通过解离保护基团式III所得到的化合物可以转化成白藜芦醇,如果希望的话,通过酯化羟基,可以转化成白藜芦醇酯。被保护羟基的Z和Z1的解离可以通过以上所引用的本身已知的方法来完成。解离被保护羟基(例如乙酰氧基)可以通过例如碱水解,比如在高温下用醇式碱金属氢氧化物处理来完成。在本发明的优选的方面中,被保护羟基是乙酰氧基,其在基本上中性条件下水解。用乙酸铵处理式III化合物,其中Z和Z1或Z、Z1和R1是乙酰氧基,可以实现这种水解,例如通过在大约室温下或不高于沸点高温下将乙酸铵水溶液(不高于60%)加到式III化合物的例如甲醇或乙醇的适当溶剂的溶液中,可参见Tetrahedron 59(2003)1049-1054。解离保护基团以后,通过酸化(碱水解后)和用例如乙酸乙酯的有机溶剂萃取可以从反应混合物中分别离析出白藜芦醇和Piceatannol。如果希望的话,白藜芦醇和Piceatannol通过采用适当的酸酯化可以转化成酯或者通过本身已知的方法转化成其活性衍生物或者它可以进行异构化。
白藜芦醇和Piceatannol的酯分别可以由未取代或取代的直链或分枝的具有1到26个碳原子的烷基衍生,或者由未取代或取代的直链或分枝的具有1到26个碳原子的脂族、芳烷基或芳族羧酸衍生。
尽管通过本发明的方法得到的(E)-白藜芦醇或(E)-Piceatannol是唯一的反应产物或基本上唯一的反应产物,如果希望的话,通过已知的方法(E)-异构体可以异构化成(Z)-异构体,参见例如Agric.Food Chem.43;1995;1820-1823。
在本发明的另一方面中,在以上反应中使用的式I化合物由式IV化合物制备。
其中Z如上定义。
更具体的是,根据本发明的这个方面,式I化合物通过还原式IV化合物得到式V化合物
其中Z如上定义,
并将式V化合物脱水来制备。
可以通过催化氢化,例如采用贵金属催化剂,比如炭负载Pd或Pt,或者活化Ni催化剂,比如Raney Ni在醇(例如甲醇)中的溶液,将式IV化合物还原以形成式V化合物。氢化反应条件不是严格限制的,该氢化反应可以在常压或高压下实施。合适的是,在贵金属催化剂的存在下使用H2在高氢气压力下,例如高达200bar,具体的是,在约10bar到约30bar氢气,和在约20℃到约50℃的温度下实施氢化。式V化合物是新化合物,它同样也是本发明的目的。通过传统的方法,例如通过反应溶液硅胶色谱可以将其离析。式IV化合物是已知的,或者可以由已知的二羟基苯乙酮以本身已知的方式通过保护羟基来制备,见上。通过本身已知的醇转化成烯烃的过程,式V化合物可以转化成式I化合物。合适的是,式V化合物的羟基首先转化成离去基团生成式VI的化合物
其中Y是离去基团,Z如上定义,
接着消去该离去基团。在此反应步骤中离去基团实例是卤素,例如氯或溴;或酯基,具体的是磺酸基,比如对甲苯磺酸基或甲磺酸基,或羧酸酯基,比如乙酰氧基;或碳酸酯;或黄原酸酯。采用传统的方法可以引入和消去离去基团。因此,式V化合物可以与卤化剂反应,例如与三溴化磷,生成式VI化合物,其中Y是溴。采用脱氢卤化剂,比如LiBr/Li2CO3,处理式VI化合物制备式I化合物。式V化合物脱氢生成式I化合物也可以通过以下方法来实现,将羟基与活性磺酸衍生物比如甲磺酰或苯磺酰卤化物或酸酐酯化以生成式VI化合物,其中Y是用于酯化式IV中的羟基的磺酸衍生物的磺酸基部分。而且,式V化合物可以与例如氯甲酸乙酯的氯甲酸烷基酯反应生成式VI化合物,其中Y是(烷基-O-CO-O-)。
式VI化合物(其中Y是酯基),转化成式I化合物适于在适当的惰性、酸稳定有机溶剂中在不高于使用溶剂的沸点的温度下实施,该有机溶剂可以是非极性溶剂,例如烃(比如甲苯),或卤化烃(比如二氯甲烷),或者是极性溶剂,比如酯(例如乙酸乙酯)或胺(例如DMF或NMP)或二甲亚砜。所述转化也可以在气相实施,例如在800℃的温度下,如果希望的话,也可以以连续模式实施。如果Y表示(烷基-OCOO-),那么从化合物VI热解消去离去基团Y特别适合。可以理解,本领域技术人员可以容易确定裂解具体离去基团的合适条件。
式VI化合物是新的化合物,这同样也是本发明的目的。
而且,将式V化合物转化成式I化合物也可以直接通过采用无机酸,比如硫酸或氢化硫酸盐或磷酸;或有机酸,比如甲酸或对-甲苯磺酸;或酸性离子交换树脂处理式V化合物完成,所述酸或树脂可以以催化量或以高达等摩尔量使用。
