| abstract | In a process for the preparation of novel compounds of the formula (Ia), either (A) a compound of the formula (IV) is acylated, or (B) a compound of the formula (VII) is oximated, or (C) a compound of the formula (IX) is methylated, or (D) a compound of the formula (XIII) is isomerized, after which, if necessary and required, one of the following reactions is carried out in a suitable sequence: (i) conversion of a ceph-2-em isomer into the required ceph-3-em isomer, (ii) reduction of a compound in which B is > S --> O to form a compound in which B is > 5 (iii) removal of any N-protecting groups or (iv) as concluding step isolation of a compound of the formula (Ia) in essentially amorphous form from a solution thereof. <IMAGE> |
