Relevant academic research and scientific papers

Synthetic carbapenem antibiotics III. 1-Methyl thienamycin

Total syntheses of 1α- and 1β-methyl thienamycin are reported. 1β-Methyl thienamycin retains the antibacterial activity of thienamycin and is highly resistant to hydrolysis by HPD-1 enzyme.

Synthetic study of 1-substituted carbapenem antibiotics

Total synthesis of 1-substituted carbapenems is described. The key step is the reaction of acetoxyazetidinone with ketene silyl acetal.
