“…Some stereochemical assignments are provisional and some of the sulfoxide stereochemistries are unknown. Thienamycin, N-acetyl-thienamycin, N-acetyl-dehydro-thienamycin, 8-epi-thienamycin, northienamycin, and NS-5 were all isolated from wildtype or a mutant of S. cattleya 81,82,[726][727][728]. Thienamycin was also isolated from S. penemijaciens 729.…”

The β-lactam antibiotics and related β-lactamase inhibitors are amongst the most important small molecules in clinical use. Most, but not all, β-lactams including penicillins, cephalosporins, and clavulanic acid are produced via fermentation or via modification of fermented intermediates, with important exceptions being the carbapenems and aztreonam. The desire for more efficient routes to existing antibiotics and for access to new and synthetically challenging ones stimulates continued interest in β-lactam biosynthesis. We review knowledge of the pathways leading to β-lactam antibiotics focusing on the mechanisms, structures and biocatalytic applications of the enzymes involved.

“…For example, NH4HF2 dissolved in formamide with the water content maintained at about 1% (41), and solutions of sodium salts of fluorinated aliphatic acids in DMF containing no more than 4% water (42) have been successfully used for this purpose. Apparently the only way aqueous solutions can be used is when a very high concentration of HF is the principal active component (43).…”
