    摘要: The invention relates to a new process for the production of intermediates for the synthesis of caephalosporin of formula (I) wherein R1, R2 and R3, independently of one another, are alkyl, alkenyl, aryl, hydroxy(C1-6)alkyl, carbamoyl-(C1-6)alkyl, amino-(C1-6)alkyl, acylamino-(C1-6)alkyl or carboxy(C1-6)alkyl, or wherein R2 and R3 together with the adjacent nitrogen atom, form an alicyclic 5- to 8-membered heterocyclic ring, and R1 signifies alkyl, alkenyl or aryl. The process according to the invention is notable in that the formation of undesired by-products, especially Δ2-analogous compounds of formula (I), is greatly reduced.
