A new component for the solid phase peptide synthesis of lipopeptide, 2-[(4R,5R)-5-({[(9H-fluoren-9-yl)methoxy]carbonylaminomethyl}-2,2-dimethyl-1,3-dioxolan-4-yl)methoxy]acetic acid (2), was designed and synthesized from (-)-2,3-O-isopropylidene-D-threitol (3) in 4 steps. The key step was the selective alkylation of 3 with benzyl bromoacetate in the presence of

In this study, we report the synthesis of several amine-spacered conjugates of ursolic acid (UA) and 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA). Thus, a total of 11 UA-DOTA conjugates were prepared holding various oligo-methylene diamine spacers as well as different substituents at the
