Abstract

13‐O‐β‐D‐Glucopyranosylgibberellin A~5~ β‐D‐glucopyranosyl ester (2a) was synthesized by base‐catalyzed (triethylamine) reaction of gibberellin A~5~ 13‐O‐β‐D‐glucopyranoside (4a) with α‐acetobromoglucose followed by mild sodium methanolate deacetylation. Structures of the gibberellin A~5~ glucosyl conjugates were established by LSI‐MS, ESI‐MS, and ^1^H‐NMR spectroscopy.
