一種2?苯基?1,2?二氫萘?1?醇外消旋化合物及其衍生物的合成方法與流程

本發(fā)明涉及二氫化萘結(jié)構(gòu)單元中間體的合成技術(shù)領(lǐng)域,尤其涉及一種2-苯基-1,2-二氫萘-1-醇外消旋化合物及其衍生物的合成方法,以及通過該方法合成新的2-苯基-1,2-二氫萘-1-醇外消旋化合物或其衍生物。



背景技術(shù):

四氫化萘結(jié)構(gòu)單元是許多具有生物活性的天然產(chǎn)物及藥物分子中常見的骨架之一,在許多腎上腺激素、抗生素以及中國紫杉醇中的異紫杉脂素、去氧鬼臼素葡萄糖酯苷等化合物中都含有四氫化萘基本結(jié)構(gòu)。這類化合物具有許多特殊的生理活性和藥理活性,如抗抑郁、消炎止痛、抗帕金森、抗癌等。相應(yīng)的合成研究也因此受到化學(xué)家們的廣泛關(guān)注,過渡金屬催化氧(氮)雜二環(huán)烯烴的不對稱開環(huán)反應(yīng)是一種合成此類手性藥物中間體的一種方法,它可以通過一步開環(huán)反應(yīng)構(gòu)建兩個手性碳中心。在手性過渡金屬配合物的催化下,氧(氮)雜二環(huán)烯烴與親核試劑發(fā)生開環(huán)反應(yīng),可以得到一種高對映立體選擇性、具有兩個手性中心的二氫化萘骨架單元的開環(huán)產(chǎn)物。該產(chǎn)物具有四種立體化學(xué)結(jié)構(gòu)構(gòu)型,分別為1,2-(r,r)、1,2-(s,s)、1,2-(r,s)和1,2-(s,r)。由于此類開環(huán)反應(yīng)具有催化劑用量少、產(chǎn)率高和對映選擇性高等特點(diǎn),化學(xué)家們對此產(chǎn)生了濃厚的興趣,并取得了很好的研究結(jié)果。過渡金屬ni、cu、ru、rh、ir、pt和pd催化氧(氮)雜二環(huán)烯烴的開環(huán)反應(yīng),具有較好的區(qū)域選擇性、對映選擇性和手性誘導(dǎo)立體控制,其中,常用的親核試劑主要包括有機(jī)鋅試劑、有機(jī)鋁試劑、有機(jī)鋰試劑、有機(jī)硼酸試劑、格利雅試劑、炔烴試劑等。但是,盡管目前已合成出多種有效的過渡金屬配合物催化劑應(yīng)用于氧(氮)雜二環(huán)烯烴開環(huán)反應(yīng)的研究,但沒有任何一種催化劑能適用于所有底物與不同的親核試劑的開環(huán)反應(yīng)。因此,研究高立體化學(xué)選擇性、高對映選擇性、高催化活性的過渡金屬配合物催化劑,實(shí)現(xiàn)高效立體選擇性的開環(huán)反應(yīng),探索出更適合的反應(yīng)條件,仍然是將來需要研究的重點(diǎn)課題。



技術(shù)實(shí)現(xiàn)要素:

本發(fā)明針對現(xiàn)有技術(shù)使用氧雜苯并降冰片烯與芳基亞磺酸鈉合成外消旋化合物時(shí)存在產(chǎn)率低的問題,提供一種使用氧雜苯并降冰片烯與芳基亞磺酸鈉可高效合成2-苯基-1,2-二氫萘-1-醇外消旋化合物及其衍生物的方法。

為實(shí)現(xiàn)上述目的,本發(fā)明采用以下技術(shù)方案。

一種2-苯基-1,2-二氫萘-1-醇外消旋化合物及其衍生物的合成方法,包括以下步驟:

s2、向催化體系中加入反應(yīng)物氧雜苯并降冰片烯和芳基亞磺酸鈉,得反應(yīng)體系,使反應(yīng)體系在50-80℃下反應(yīng);所述氧雜苯并降冰片烯與芳基亞磺酸鈉的物質(zhì)的量之比為1:1-3,所述氧雜苯并降冰片烯與pt(cod)cl2的物質(zhì)的量之比為100:2.5-10。

所述氧雜苯并降冰片烯的結(jié)構(gòu)如下:

其中,r1為h或鹵素,r2為h或烷氧基。

具體的,所述鹵素為br;所述烷氧基為och3。

所述芳基亞磺酸鈉鹽為c6h5so2na、4-fc6h4so2na、4-clc6h4so2na、4-brc6h4so2na、3-clc6h4so2na、2-clc6h4so2na、4-h3cc6h4so2na、4-o2nc6h4so2na、4-f3cc6h4so2na、2,5-(ch3)2c6h4so2na、2,4,6-(ch3)3c6h4so2na、1-萘亞磺酸鈉或2-萘亞磺酸鈉。

s3、反應(yīng)至反應(yīng)體系中的反應(yīng)物消失或濃度不再變化時(shí),將反應(yīng)體系冷卻至室溫,然后分離提純產(chǎn)物,收集2-苯基-1,2-二氫萘-1-醇外消旋化合物或其衍生物。

具體的,步驟s3中,反應(yīng)體系冷卻至室溫后,先真空濃縮除去溶劑,殘留物再通過柱層析色譜法純化,收集2-苯基-1,2-二氫萘-1-醇外消旋化合物或其衍生物。

通過以上方法合成了新的2-苯基-1,2-二氫萘-1-醇外消旋化合物或其衍生物,所述化合物的結(jié)構(gòu)如下:

與現(xiàn)有技術(shù)相比,本發(fā)明的有益效果是:本發(fā)明以pt(cod)cl2與有機(jī)配體形成的過渡金屬配合物作為催化劑,催化氧雜苯并降冰片烯與芳基亞磺酸鈉反應(yīng),可高效合成2-苯基-1,2-二氫萘-1-醇外消旋化合物或其衍生物,且反應(yīng)條件溫和,在50-80℃下即可完成反應(yīng)。當(dāng)以適量的pph3作為有機(jī)配體與pt(cod)cl2形成過渡金屬配合物催化劑且同時(shí)使用添加劑agsbf6,并以ch3oh為溶劑時(shí),反應(yīng)時(shí)間短,且合成2-苯基-1,2-二氫萘-1-醇外消旋化合物的產(chǎn)率可高達(dá)92%。
