Process for the preparation of optically Active cyclic depsipeptides, annular, with 24 Atoms containing phenyl lactic acid and lactic acid, using fungal strains of the species and other xilariaceos Rosellinia

摘要

These strains grow on living wood, needles and enzyme preparations isolated from these fungal strains. Pfos-1022a (1) is very suitable for the treatment of endocrine parasites, especially in the medical and veterinary fields. Requirements 1: procedure f or prepare PF 1022A o f the form (1) of a circular octadiphenyl ether with 24 atoms, using rosellinia specialties and other Gen es of xylariaceae family, or through separate Enzi m preparation from these physics
