4-nitrobenzyl (1R, 5S,6S)-2-(2-diethylcarbamoylphenylsulfinyl)-1-methyl-6-[1(R)-t-butyldimethylsilyloxyethyl]-1-carbapen-2-em-3-carboxylate → 4-Nitrobenzyl (1R, 5S,6S)-2-[2-(1-perhydroazepinylcarbonyl)phenylthio]-1-methyl-6-[1(R)-t-butyldimethylsilyloxyethyl]-1-carbapen-2-em-3-carboxylate

Participants

Reaction Steps

Following a procedure similar to that described in Example 18, but using 4-nitrobenzyl (1R,5S,6S)-2-(2-diethylcarbamoylphenylsulfinyl)-1-methyl-6-[1(R)-t-butyldimethylsilyloxyethyl]-1-carbapen-2-em-3-carboxylate (prepared as described in Example 39) and 2-(1-perhydroazepinylcarbonyl) phenylmercaptan as starting materials, in relative proportions similar to those used in that Example, the title compound was obtained in a yield of 95%. This compound was found to be the same as the compound prepared as described in Example 36 and had the same physicochemical properties.
