A convenient stereoselective synthesis of (3R,5R)-carbapenam-3-carboxylic acid from D-(R)-glutamic acid is described and the product shown to be enantiomeric with that isolated from Serratia and Erwinia species; this represents the first naturally occurring carbapenem or carbapenam with (5S) ring junction geometry to be reported.
