本發(fā)明涉及雜環(huán)化合物和有機(jī)化學(xué)合成領(lǐng)域,具體涉及一種螺[3,5'-吡咯[2,1-a]異喹啉-氧化吲哚]類化合物及其制備方法。
背景技術(shù):
運(yùn)用簡(jiǎn)單易得的原料合成結(jié)構(gòu)多樣化的含氮雜環(huán)化合物一直是有機(jī)化學(xué)界關(guān)注的焦點(diǎn)。含有吡啶并吡咯環(huán)的吲嗪骨架是構(gòu)成天然生物堿的核心結(jié)構(gòu)單元,含有這種雜環(huán)骨架的化合物往往具有良好的生物活性和潛在的藥物價(jià)值。目前,吲嗪類衍生物的獲得主要通過(guò)從天然產(chǎn)物中提取分離或人工合成的方法實(shí)現(xiàn)。其中,人工合成的方法日益重要,主要包括基于吡咯或異喹啉骨架的分子內(nèi)環(huán)化反應(yīng)、吡咯或不飽和胺的串聯(lián)環(huán)化反應(yīng)等。
然而,現(xiàn)有的人工合成技術(shù)仍存在一定的局限性,如合成的吲嗪類衍生物,除吲嗪基本骨架外,主要是一些支鏈或并環(huán)結(jié)構(gòu),其結(jié)構(gòu)類型不夠廣泛。對(duì)于空間結(jié)構(gòu)更為復(fù)雜的吲嗪類衍生物,尤其是含螺環(huán)結(jié)構(gòu)的吲嗪類衍生物的合成,仍是一項(xiàng)挑戰(zhàn)性的工作。而且從藥物的設(shè)計(jì)與構(gòu)效關(guān)系的角度考慮,含螺環(huán)結(jié)構(gòu)的化合物由于其獨(dú)特的三維構(gòu)象,在空間上更容易與靶點(diǎn)結(jié)合,往往具有更好的藥物活性。因此,發(fā)展簡(jiǎn)便、高效的合成技術(shù)實(shí)現(xiàn)結(jié)構(gòu)新穎的螺環(huán)吲嗪類衍生物的合成具有重要意義。
