allyl (1R,5S,6S)-2-diphenoxyphosphoryloxy-6-[(R)-1-hydroxyethyl]-1-methyl-1-carbapen-2-em-3-carboxylate → allyl (1R,5S,6S)-2-[(2S,4S)-N-allyloxycarbonyl-2-(2,5-dioxopyrrolidin-3-yl)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 (230 mg, 0.46 mmol) and (2S,4S)-N-allyloxycarbonyl-2-(2,5-dioxopyrrolidin-3-yl)-4-mercaptopyrrolidine (130 mg, 0.46 mmol, compound of Reference Example 9) to obtain allyl (1R,5S,6S)-2-[(2S,4S)-N-allyloxycarbonyl-2-(2,5-dioxopyrrolidin-3-yl)pyrrolidin-4-ylthio]-6-[(R)-1-hydroxyethyl]-1-methyl-1-carbapen-2-em-3-carboxylate (125 mg, yield: 50.9%).
