專利名稱::一種立體專一性的合成環(huán)狀亞砜亞胺、亞磺酰胺、磺酰胺的方法
技術(shù)領(lǐng)域:
:本發(fā)明涉及一種高效的制備環(huán)狀亞砜亞胺、環(huán)狀亞磺酰胺、環(huán)狀磺酰胺的方法。該方法得到的環(huán)狀化合物在不對稱合成、含氟藥物以及含氟材料領(lǐng)域中有著非常廣泛的應(yīng)用。
背景技術(shù):
:含氟化合物在藥物設(shè)計和材料化學(xué)中有著重要的應(yīng)用。選擇性地向有機分子中引入氟原子或含氟基團,可以大大提高母體分子原有的生理活性。因此,選擇性氟化和氟垸基化反應(yīng)的研究在農(nóng)藥、醫(yī)藥以及材料科學(xué)領(lǐng)域中也受到人們越來越多的關(guān)注。盡管氟化、三氟甲基化反應(yīng)的研究已經(jīng)相當(dāng)成熟,但是二氟甲基化反應(yīng)的研究仍然相對較少。由于二氟甲基(-CF2H)和羥甲基(-CH2OH)具有最相近的等極性和等體性,并且還可以作為親酯性的氫鍵供體,因此,含二氟甲基的化合物在生命科學(xué)領(lǐng)域中具有重要的研究價值。環(huán)狀亞砜亞胺1是一類重要的有機化合物然而對于此類化合物,文獻(xiàn)中的相關(guān)報道卻非常少,僅在JOg.CZem.1978,43,1824.有一例報道,該方法從鄰甲N-、1<formula>formulaseeoriginaldocumentpage4</formula>硫基苯甲醇出發(fā),需要經(jīng)過氯化、氧化、亞胺化等一系列轉(zhuǎn)化,最終以很低的產(chǎn)率得到環(huán)狀亞砜亞胺。然而對于環(huán)狀含氟亞砜亞胺文獻(xiàn)卻一直沒有報道。環(huán)狀亞磺酰胺2也是一類重要的有機化合物,盡管文獻(xiàn)C/ze肌五d2<formula>formulaseeoriginaldocumentpage4</formula>2006,",633.對這類化合物的合成有相關(guān)的報道,但由于自由基反應(yīng)存在的缺陷,使得從該方法制備環(huán)狀亞磺酰胺受到了很大的限制,并且對于環(huán)狀含氟亞磺酰胺,文獻(xiàn)一直沒有報道。在本文中,我們對環(huán)狀含氟亞砜亞胺進行轉(zhuǎn)化,幾乎以定量的產(chǎn)率得到環(huán)狀含氟亞磺酰胺。環(huán)狀磺酰胺3也是一類重要的有機化合物,作為磺胺類藥物在生命科學(xué)領(lǐng)域中得到了廣泛的應(yīng)用。根據(jù)文獻(xiàn)JOg.1997,62,7047.報道的方法,以saccharin(糖精)為起始原料,經(jīng)過親核加成、不對稱氫化等步驟可以合成環(huán)狀磺酰胺,但該方法成本較高,產(chǎn)率較低。在本文中,本發(fā)明人對環(huán)狀亞磺酰胺進行氧化,可以高效地得到相應(yīng)的環(huán)狀磺酰胺。
