A highly convergent four-component, two-step, one-pot reaction between an aldehyde, a primary amine, an alkyl-β-(N,N-dimethylamino)-α-isocyanoacrylate and hydrazoic acid to form a substituted bicyclic tetrazole is disclosed. Vast arrays of small organic « drug-like å molecules can be combinatorially prepared with such transformation.
公开了醛,伯胺,烷基-β-(N,N-二甲基氨基)-α-异氰基丙烯酸酯和肼酸之间的高度收敛的四组分,两步一锅法反应,以形成取代的双环四唑。通过这种转化,可以组合制备大量的小型有机“类药物”小分子。
