A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 82294-70-0, Name is 4-Methylthiazole-5-carbaldehyde, molecular formula is C5H5NOS. In a Article£¬once mentioned of 82294-70-0, HPLC of Formula: C5H5NOS
An efficient chemoenzymatic process has been developed for preparation of 7-amino-3-[Z-2-(4-methylthiazol-5-yl)vinyl]-3-cephem-4-carboxylic acid, featuring removal of para-methoxybenzyl by trichloroacetic acid and cleavage of phenylacetyl E-isomer by immobilized penicillin acylase enzyme. The E-isomer of 7-amino-3-[Z-2-(4-methylthiazol-5-yl)vinyl]-3-cephem-4-carboxylic acid could be easily decreased to less than 0.2 % by salt formation. Importantly, trichloroacetic acid and immobilized penicillin acylase enzyme could be recovered and reused. The enzyme reaction could be run in a flow reactor. Only two crystallizations are involved as the purification procedure in the six-step sequence.
