Synthesis and in vitro activity of several new carbapenems
Keyword(s):
The synthesis and in vitro activity of several new carbapenems, 2-(3-cis-substituted cyclopentylthio)- and 2-(4-cis-substituted cyclohexylthio)-(6S)-[(1′R)-hydroxyethyl]-(5R)-carbapen-2-em-3-carboxylic acids 7 and 8, are described. The synthesis involves the stereospecific preparation of cis-substituted cyclopentyl- and cyclohexylthiols 2 and 3 by the hetero Diels–Alder reaction followed by some chemical manipulations.
