A systematic study of the base-catalysed exchange reactions of a series of gibberellin 7-methyl esters reveals that exchange of the 6-proton for deuterium is apparent only in compounds possessing a 19,10-gamma-lactone or the analogous 19-ketone, The favoured mechanism for the participation of the 19-carbonyl function involves attack of the base on the 19-carbonyl giving a tetrahedral intermediate which may then abstract the 6-alpha-proton (Scheme 2).
