allyl (1S,5R,6S)-2-(hydroxymethyl)-6-[1(R)-allyloxycarbonyloxy-ethyl]-1-methylcarbapen-2-em-3-carboxylate → (1S,5R,6S)-6-[(1R)-1-hydroxyethyl]-2-(3-phenylimidazo[5,1-b]thiazolium-6-yl)methyl-1-methyl-1-carbapen-2-em-3-carboxylate

Participants

Reaction Steps

The same procedure as in Example 1 was repeated except that 104 mg of allyl (1S,5R,6S)-6-[(1R)-1-allyloxycarbonyloxyethyl]-2-hydroxymethyl-1-methyl-1-carbapen-2-em-3-carboxylate and 86 mg of 3-phenylimidazo[5,1-b]thiazole were used, thereby obtaining 16.2 mg of the title compound.
