Partial synthesis of [17-13C; 15,17-3H]gibberellin A29 from gibberellin A3
Abstract
The preparation of [17-13C]gibberellin A29, containing 96.8 atoms %13C, from gibberellin A3 in fourteen steps in 0.55% overall yield is described. [17-13C; 15,17-3H]Gibberellin A29, containing 90.6 atoms %13C and with a specific radioactivity of 29.8 mCi mmol–1, is also described.
The ready conversion of 2,O2-didehydrogibberellin A29 by aqueous alkali to a known catabolite of gibberellin A29 is noted.
