Add time:08/24/2019 Source:sciencedirect.com
N-Methoxymethyl-N-methylcarbamoyl(trimethyl)silane reacted with N-sulfonylimines in anhydrous benzene under catalyst-free conditions to afford α-(N-sulfonyl)amino-N-methoxymethyl-N-methylamides in good to excellent yields (71–95%). Furthermore, after acid hydrolysis at room temperature, the corresponding α-(N-sulfonyl)amino secondary amides can be formed.
