Synthesis of the β‐D‐glucosyl ester of [carbonyl13C]‐indole‐3‐acetic acid

Abstract
An efficient, operationally simple synthetic approach to 1‐O‐([carbonyl13C]‐indole‐3′‐ylacetyl)‐β‐D‐glucopyranose is described. The synthesis was carried out by fusing a fully benzylated 1‐O‐glucosylpseudourea intermediate with [carbonyl13C]‐indole‐3‐acetic acid, followed by hydrogenolytic removal of the protective groups.
