We disclose a direct approach to the diastereoselective synthesis of phosphorus substituted -acylaziridines based on a one-pot ZnCl-catalyzed Joullié-Ugi three-component reaction of phosphorylated 2-azirines, carboxylic acids and isocyanides. Hence, this robust protocol offers rapid access to an array of -acylaziridines in moderate-to-good yields and up to 98:2 dr for substrates over a wide scope. The relevance of this synthetic methodology was achieved via a gram-scale reaction and the further derivatization of the nitrogen-containing three-membered heterocycle.

SARS-CoV-2 infection causes a wide spectrum of symptoms with varying degrees of severity, from asymptomatic cases or cases in the form of self-limiting influenza-like illness to cases of rapidly progressing respiratory distress syndrome due to an anomalous immune system response in the form of a cytokine storm. Thrombotic complications are also common. Multiple antiviral treatments have been tested in COVID-19 without favorable outcomes.

Viruses are becoming more and more important as etiological agents of pneumonia, mainly due to improvements in diagnostic techniques. At present, they account for approximately one-third of community-acquired pneumonia cases. They tend to occur in children and elderly patients, causing anything from mild cases to severe cases which require intubation and intensive care.
