| titleOfInvention | Production process of intermediates for use in the synthesis of cephalosporin |
| abstract | The present invention relates to a compound of formula (I) Wherein R 1 , R 2 and R 3 are independently of each other an akyryl, alkenyl, aryl, hydroxy (C 1-6 ) alkyl, carbamoyl- (C 1-6 ) alkyl, amino- (C 1-6 ) alkyl, aclamino- (C 1-6 ) alkyl or carboxy (C 1-6 ) alkyl, or R 2 and R 3 together with the adjacent nitrogen atom Relates to a novel process for the production of intermediates for the synthesis of cephalosporins of the formula 5-membered to 8-membered heterocycles, R 1 represents alkyl, alkenyl or aryl. The process according to the invention is notable in that it significantly reduces the formation of undesirable by-products, in particular Δ2-analogue compounds of the formula (I). |
