allyl (1R,5S,6S)-2-diphenoxyphosphoryloxy-6-[(R)-1-hydroxyethyl]-1-methyl-1-carbapen-2-em-3-carboxylate → allyl (1R,5S,6S)-2-[(2R,4S)-N-allyloxycarbonyl-2-(2,4-dioxoimidazolidin-5-ylmethyl)pyrrolidin-4-ylthio]-6-[(R)-1-hydroxyethyl]-1-methyl-1-carbapen-2-em-3-carboxylate

Participants

Reaction Steps

The same procedure as in Example 8-1 was carried out by using allyl (1R,5S,6S)-2-diphenoxyphosphoryloxy-6-[(R)-1-hydroxyethyl]-1-methyl-1-carbapen-2-em-3-carboxylate (220 mg, 0.440 mmol) and (2R,4S)-N-allyloxycarbonyl-2-(2,4-dioxoimidazolidin-5-ylmethyl)-4-tritylthiopyrrolidine diastereomer A (270 mg, 0.498 mmol, compound of Reference Example 29) to obtain allyl (1R,5S,6S)-2-[(2R,4S)-N-allyloxycarbonyl-2-(2,4-dioxoimidazolidin-5-ylmethyl)pyrrolidin-4-ylthio]-6-[(R)-1-hydroxyethyl]-1-methyl-1-carbapen-2-em-3-carboxylate diastereomer A (70 mg, yield: 26%).
