Multicomponent reactions (MCRs), followed by subsequent transformations, are fascinating tools for the rapid and effective synthesis of molecular scaffolds with potential pharmacological relevance. We became interested in the preparation of novel 5-aroyl-1-aryltetrazoles as (1) they still represent challenging structures not easily accessible through the methods described in literature, and (2) the α-ketotetrazolic framework may be considered as a potential bioisostere of the enonic linker of chalcones. In the present work, a novel, simple, effective and general synthesis for this class of compounds is described.
多组分反应(MCRs)及其后续转化是快速有效合成具有潜在药理学意义的分子骨架的迷人工具。我们对制备新型的5-芳酰基-1-芳基四唑产生了兴趣,原因有二:(1)这些结构在当前文献所描述的方法下仍被视为难以获得的具有挑战性的结构;(2)α-酮基四唑框架可能被认为是一种潜在的查尔酮连接子生物电子等排体。本工作中描述了一种新颖、简单、高效且通用的此类化合物的合成方法。
