Abstract

A jelen találmány az (IA) és/vagy az (IB) általános képletű vegyületelőállításával kapcsolatos, ahol az említett általános képletben njelentése 0 vagy 1; R1 csoport jelentése hidrogénatom vagyhidroxicsoport; R2 csoport jelentése hidrogénatom; vagy ha n jelentése0; akkor R1 és R2 csoportok együttesen az R1 csoporttal és R2csoporttal rendelkező szénatomok közötti második kémiai kötésbőlszármaznak, feltéve, hogy ha n jelentése 1, akkor R1 és R2 csoportokjelentése hidrogénatom; R3 csoport jelentése -COOH csoport, vagy -COOR4 csoport; R4 csoport jelentése alkilcsoport vagy arilcsoport; A,B és D gyűrűik szubsztituensei, melyek mindegyike lehet azonos vagyeltérő, és jelentésük vagy hidrogénatom, vagy halogénatom, vagyalkilcsoport, vagy hidroxicsoport, vagy alkoxicsoport. Ez az eljárásmagába foglalja a (IIA) és/vagy a (IIB) általános képletű kiindulásivegyület - ahol az említett általános képletben R3 jelentése -CH3-csoport, és R1, R2, A, B és D jelentése a fentiek szerinti - egymikroorganizmus jelenlétében a vegyület előállításához hatékonykörülmények között történő inkubálását. A mikroorganizmus jelenthetStreptomyces-t, Stemphylium-ot, Gliocladium-ot, Bacillus-t, Botrytis-tCyathus-t, Rhizopus-t, Pycnidiosphora-t, Pseudomonas-t, Helicostylum-ot, Aspergillust, Mucor-t, Gelasinospora-t, Rhodotorula-t, Candida-t,Mycobacterium-ot vagy Penicillium-ot. Alternatív lehetőségként amikroorganizmus lehet Cunninghamella bainieri. Ó
