The benzyl esters 1- 3 of oligo[(R)-3-hydroxybutanoic acids] (OHB) containing 2, 16, or 32 HB units were coupled at the hydroxy terminus with arginine (by esterification with carbodiimide), with glucose (by acetalization with glucosyl trichloroacetimidate), and with 7- (dimethylamino)coumarin-4-acetic acid and biotin (by amide formation through a glycine linker) to give, after deprotection(s), the corresponding 'labelled' OHB acids 7-9, 12, 13, 25, 26, 33, and 34 (Schemes 1, 4, and 5). The respective novel 16- and 32mer derivatives exhibit distinct water solubility (Table) or may be detected (in minute amounts) by fluorescence spectroscopy, properties required for biochemical investigations.
