The invention discloses aza-2-
ketone derivatives, a synthesis method thereof and application of the aza-2-
ketone derivatives in preparation of drugs. According to the invention, an alpha-carbonyl acyl
silane compound is taken as a
raw material, and under illumination, the alpha-carbonyl acyl
silane compound and a vinyl
aziridine compound are subjected to [5 + 2]
cycloaddition reaction, so that a series of aza-2-
ketone derivatives with different structures are simply and efficiently synthesized. The aza-2-ketone derivative disclosed by the invention can be further converted into
medicine molecules such as kappa-
opioid receptor selective
agonist molecules and the like. The method has the advantages of easily available raw materials, simple operation, mild
reaction conditions, and diversity of functional groups.
