Synthesis intermediate for thienamycin and its production |
| abstract |
NEW MATERIAL: A compound of formula I (R is a protecting group). n EXAMPLE: (3R,4R)-3-[(R)-1-hydroxyethyl]-4-[3-(4-nitrobenzyl)oxycarbonyl-2-oxo-3- diazopropyl]azetidin-2-one. n USE: An intermediate for total synthesis of an antibiotic thienamycin starting with Laspartic acid. n PROCESS: A compound of formula II is treated with an azide (e.g. p- carboxybenzenesulfonyl azide, methanesulfonyl azide) in a solvent (e.g. acetonitrile, THF) in the presence of a base (e.g. triethylamine, pyridine). n COPYRIGHT: (C)1991,JPO |
