反応手順
A similar cultivation and reaction as in Example 1 was carried out by substituting L-leucine as the isovaleryl donor for DL-norvaline. From 60 g of tylosin and 15 g of L-leucine, about 900 mg of white crystals of 4"-isovaleryltylosin and 17 g of white crystals of 3-acetyltylosin were obtained.
