SYNTHESIS OF THE β-LACTAM ANTIBIOTIC (+)-THIENAMYCIN VIA AN INTERMEDIATE ?-ALLYLTRICARBONYLIRON LACTONE COMPLEXES

The ?-allyltricarbonyliron lactone complex (7), formed by reaction of E-1,2-epoxy-2-methyl-6,6-dimethoxyhex-3-ene (5) with co-ordinatively unsaturated iron carbonyl species, was reacted with benzylamine to give a lactam complex (8) by an SN'-like mechanis

An Asymmetric Synthesis of Synthetic Intermediates to Thienamycin and Epithienamycins A and B

An asymmetric synthesis for the synthetic intermediates to carbapenem antibiotics was examined via isoxazoline derivatives prepared by 1,3-dipolar cycloaddition between the nitrile oxide and menthyl crotonate.The (4S)-trans-azetidinone (14) having the ant
