The present invention relates to an efficient process of synthesizing some known Ertapenem compounds and to provide new intermediate compounds of Meropenem and Doripenem. The process and the intermediate can substantially increase the effective yield and reduce the impurity generation. The present invention further provides a novel and effective process for recovering and purifying ertapenem compounds by utilizing a low cost, materials with chemical stability as a carrier for isolating ertapenem compounds from extracts.
