style="text-indent:25px">惡唑嘌呤類化合物是一類有趣的化合物，具有出色的性能。大量研究集中在其光物理應(yīng)用以及用作熒光染料或生物成像中。惡唑草嘌呤的異常結(jié)構(gòu)方面和對手性?；鹚狨サ难芯恳惨呀?jīng)出現(xiàn)。近來，已經(jīng)發(fā)現(xiàn)含有（陰離子）四面體硼的分子具有顯著的醫(yī)學(xué)價值，例如HNE或NLRP3炎性體抑活性。絕大多數(shù)已報道的惡唑硼嘌呤是通過用甲硼烷處理水楊醛亞胺以產(chǎn)生硼烷來制備的，其后不易官能化。還可以通過β-二酮與伯胺的縮合反應(yīng)以及隨后與硼烷的反應(yīng)來合成相關(guān)同類物。值得注意的是，在不對稱β二酮底物的情況下，縮合步驟中的區(qū)域選擇性問題限制了后一種方法的使用。盡管有許多報道都圍繞著氧雜硼嘌呤產(chǎn)品的性能，但是一旦安裝了硼，對其穩(wěn)定性，反應(yīng)性以及用于進一步合成轉(zhuǎn)化的潛力的了解就很少。在這種情況下，研究人員尋求新的方法以獲取更廣的惡唑嘌呤類藥物，它們可以以模塊化的方式組裝，并在后期易于功能化。證明了使用有效的過渡金屬催化重排的進入新類的惡唑諾寧。該方法克服了實現(xiàn)乙烯基N-烯丙基酰胺基材的AZA-Claisen重排的合成挑戰(zhàn)，從而產(chǎn)生各種高度可改性的惡唑尼堿產(chǎn)品。在一些新的雜環(huán)化合物的合成中使用2-氯-4H-4-Oxo-Pyrido
