INTERMEDIATES FOR THE PREPARATION OF THIENAMYCIN AND PROCESS FOR PREPARING THE SAME

摘要

Disclosed are the compounds wherein a) R<1> is hydrogen or a protecting group, R<8> is hydrogen and R<9> is -CH2I, b) R<1> is a protecting group, R<8> is R<9> and is -CH2C(SR)3 wherein R is selected from lower alkyl having 1-6 carbon atoms, aryl and aralkyl having 6 to 10 carbon atoms, and wherein R can be the same or different, c) R<1> is hydrogen, R<8> is and R<9> is -CH2-@-CH2-CO2R<7> wherein R<7> is a protecting group, d) R<1> is hydrogen, R<8> is wherein R<7> is a protecting group which are intermediates for the total synthesis of thienamycin. Further disclosed is the process for preparing such compounds.
