protocol for the synthesis of functionalized 2,4,6-triaryl pyridines and pyrimidines was developed from commercially available aromatic ketones, aldehydes and hexamethyldisilazane (HMDS) as a nitrogen source under microwave irradiation. In this multicomponent synthetic route, Lewis acids play an important role in selectively synthesizing six-membered heterocycles, including pyridines (1N) and pyrimidines
以市售芳香酮、醛和六甲基二硅氮烷 (HMDS) 作为氮源,在微波辐射下开发了一种高效通用的合成功能化 2,4,6-三芳基吡啶和嘧啶的方案。在这条多组分合成路线中,路易斯酸在选择性合成六元杂环,包括吡啶(1N)和嘧啶(2N)方面发挥着重要作用,涉及[2 + 1 + 2 + 1]或[2 + 1 + 1 + 1 + 1] 环形过程。
