p-nitrobenzyl (3R,5R,6S)-6[(R)-1-hydroxyethyl]-2-oxocarbapenam-3-carboxylate → 4-Nitrobenzyl (5r,6s)-2-[7-(2-t-butyldimethylsilyloxyethyl)thio-imidazo[5,1-b]thiazol-2-yl]-6-((1r)-1-hydroxyethyl)-1-carbapen-2-em-3-carboxylate

Participants

Reaction Steps

The procedure of Example 1a) was repeated, except that 752 mg of 4-nitrobenzyl (3R,5R,6S)-6-((1R)-1-hydroxyethyl)-2-oxo-1-carbapenam-3-carboxylate and 1.433 g of 7-(2-t-butyldimethylsilyloxyethyl)thio-2-(tri-n-butylstannyl)imidazo[5,1-b]thiazole were used as the starting compounds. Thus, 703 mg of 4-nitrobenzyl (5R,6S)-2-[7-(2-t-butyldimethylsilyloxyethyl)thioimidazo[5,1-b]thiazol-2-yl]-6-((1R)-1-hydroxyethyl)-1-carbapen-2-em-3-carboxylate was prepared.
