Patent number: 4282154Abstract: As per invention, [6--.sup.3 H] or [6--.sup.2 H] gibberellins respectively are produced. By the process as per invention, production of tagged gibberellins is made from natural gibberellins or gibberellin derivatives having a carboxyl group at position 6 of the ent-gibberellin basic skeleton. After transformation into a gibberellin derivative with a hydroxymethyl group at position 6, oxidation is made to gibberellin-7-aldehyde with subsequent conversion of same to a mixture of 6-epimeric gibberellin-7-aldehydes, which will be obtained tagged at the C-6 position if deuterium or tritium donors are present during epimerization, oxidation into tagged gibberellins being performed thereafter.By the invention, tagged gibberellins are made available which are tritiated or deuterated to such a C-H bond as is present in unsubstituted state in all natural gibberellins and their derivatives, and at which bond no biochemical changes have hitherto been observed.Type: GrantFiled: March 28, 1979Date of Patent: August 4, 1981Assignee: Akademie der Wissenschaften DERInventors: Manfred Lischewski, Gunter Adam
