Synthesis process of precursors of derivatives of beta-lactam nuclei and precursors and derivatives thereof
10385068 · 2019-08-20 ·

A synthesis process of precursors of derivatives of beta-lactam compounds, said beta-lactam compounds being selected from 6-aminopenicillanic acid and 7-aminocephalosporanic acid, preferably 6-aminopenicillanic acid, comprising the following steps: a) protection of the amine group of the beta-lactam compound, selected from 6-aminopenicillanic acid and 7-aminocephalosporanic acid, preferably 6-aminopenicillanic acid, through the formation of a carbamate by reaction with a dicarbonate; b) esterification of the carboxyl group in position 2 of the beta-lactam compound obtained in step a) by reaction with propargyl alcohol.
