Reaktionsschritte
The conversion reaction was carried out in a manner similar to Example 4 with the same strain, in which L-leucine was used in substitution for DL-norvaline in Example 4 as the isovaleryl donor. About 400 mg of white crystals of 3-acetyl-4"-isovaleryltylosin were obtained from 3 g of tylosin.
