p-nitrobenzyl (1R,5R,6S)-2-(di-phenylphosphoryloxy)-6-[(R)-1-hydroxyethyl]-1-methyl-carbapen-2-em-3-carboxylate → HCID 131721895, compound

Participants

Reaction Steps

By using 4-nitrobenzyl (1R,5R,6S)-6-[(1R)-1-hydroxyethyl]-1-methyl-2-diphenylphosphoryloxy-1-carbapen-2-em-3-carboxylate (1.53 g) and (2S,4S)-2-[(3S)-3-[(3S,4S)-5-cyclohexyl-3-hydroxy-4-(4-nitrobenzyloxycarbonyl)aminopentanoylamino]pyrrolidin-1-ylcarbonyl]-4-mercapto-1-(4-nitrobenzyloxycarbonyl)pyrrolidine (2.00 g), reaction and purification were carried out in a similar manner to that described in Example 1-(1), whereby 4-nitrobenzyl (1R,5S,6S)-6-[(1R)-1-hydroxyethyl]-2-[(2S,4S)-2-[(3S)-3-[(3S,4S)-5-cyclohexyl-3-hydroxy-4-(4-nitrobenzyloxycarbonyl)aminopentanoylamino]pyrrolidin-1-ylcarbonyl]-1-(4-nitrobenzyloxycarbonyl)pyrrolidin-4-ylthio]-1-methyl-1-carbapen-2-em-3-carboxylate (2.10 g) was obtained as an amorphous substance.
