Three syntheses of lacticolorin
Abstract
Lacticolorin (15)[2-hydroxy-4-(hydroxymethyl)phenyl 6-O-benzoyl-β-D-glucopyranoside], a metabolite from the leaves of Protea lacticolor Salisb., has been synthesized by three different routes. These comprise four- to six-step procedures and apply extended use of blocking groups, selective reactions, and chromatographic separations.
