Carbapenem antibiotics are characterized by the presence of the 7-oxo-1-azabicyclo[3.2.0]hept-2-ene-2-carboxylic acid system. These new bicyclic β-lactam antibiotics are rapidly degraded by dehydropeptidase-I. The introduction of a methyl group at t

New derivatives of L-(+)-tartaric acid have been synthesized from the monomethyl-2,3-O-isopropylidene (R,R)-(+)-tartrate by visible light photolysis of its N-hydroxy-2-thiopyridone ester derivative in presence of activated alkenes. The carbon radical

A general method for the synthesis of the title compounds is reported. The N-phenacylarylamines (11), prepared from the corresponding phenacyl bromides (9) and arylamines (10), give the thiono (or dithio) carbamates (12) on treatment with phenoxythio
