step-economical methodologies for the chemodivergent synthesis of tri-substituted pyrroles and 3-oxazolines from the domino reactions of 2H-azirines and acetone. For instance, acetone served as a nucleophile to react with 2H-azirines under the basic conditions to furnish pyrroles. Upon changing the catalyst to TfOH, acetone served as an electrophile to synthesize 3-oxazolines. Moreover, the products could
我们报告了两种实用且经济的方法,用于通过 2 H-氮丙啶和丙酮的多米诺骨牌反应化学发散合成三取代吡咯和 3-恶唑啉。例如,丙酮作为亲核试剂在碱性条件下与2H-氮丙啶反应生成吡咯。将催化剂改为 TfOH 后,丙酮作为亲电子试剂合成 3-恶唑啉。此外,该产品可以在克级合成,并提出了可能的催化循环。
