Partial synthesis of gibberellin A37 by selective reduction of the hindered 10-carboxy-group in gibberellin A13
Abstract
Selective reduction of the severely hindered 10-carboxy-group in gibberellin A13(5) has been achieved through its 20 → 3-lactonic derivative (10) in which the relevant carbonyl function is made more accessible; a partial synthesis of the new gibberellin A37(2) is thus provided.
