A PYRROLIDYLTHIOCARBAPENEM DERIVATIVE

摘要

A pyrrolidylthiocarbapenem derivative represented by Formula I is provided: wherein R<1> is hydrogen or lower alkyl; R<2>, R<3> and R<4> are hydrogen, lower alkyl which can be substituted or an amino protecting group independently, or R<2> and R<3> together with a nitrogen atom to which R<2> and R<3> are bonded form a saturated or unsaturated cyclic group, or R<2>and R<4>, or R<3> and R<4> together with two nitrogen atoms and one sulfur atom in the sufamide group form a saturated or unsaturated cyclic group; each cyclic group can further include at least one atom selected from the group consisting of oxygen, sulfur and nitrogen, and each cyclic group can be substituted; X<1> is hydrogen or a hydroxy protecting group; X<2> is hydrogen, a carboxy protecting group, an ammonio group, an alkali metal or an alkaline-earth metal; and Y<2> is hydrogen or an amino protecting group.
