easy synthesis of a broad range of β‐lactams. The synthesis involves a [3+1] cyclization of amide dianions with diiodomethane. In contrast to the seminal work of Hirai et al. from 1979, the reaction proved to be a general and efficient approach towards azetidinones. The ease of the process was confirmed by DFT calculations and its power demonstrated by a diversity‐oriented synthesis of β‐lactams with

The invention discloses a one pot process for the arylation of β-dicarbonyl compounds. Particularly, the present invention discloses transition-metal-free, chemo-selective, one pot process for the C-arylation of malonamide esters having Formula I at room temperature provide temperature range to obtain the arylated compounds of formula II with good yield, wherein the arylated compounds are selected from mono-arylated compound and di-arylated compound or mixture thereof.
