The absolute configurations of fistularin-3, 11-epi-fistularin-3, and a related bis-oxazolidinone were determined by microscale hydrolysis followed by derivatization with 1-fluoro-2,4-dinitrophenyl-5-l-alaninamide. Samples of fistularin-3 from Verongid marine sponges collected in the Great Barrier Reef (Australia), Baía de Todos os Santos (Brazil)

A high-performance liquid chromatography-electrospray ionization-mass spectrometric (LC-ESI-MS) method is presented that allows rapid and accurate determination of amino acid chiral purity in a peptide. Peptides are hydrolyzed in hydrochloric acid-d1/acetic acid-d4 and then converted to diastereomers by derivatization with 1-fluoro-2,4-dinitrophenyl-5-L-alanine

Esterification of glycosylated serine and cysteine derivatives with a 4-alkoxybenzyl alcohol (Wang) resin is described. The classical methods of ester bond formation (symmetrical anhydride, 2-(1H-benzotriazol-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate [TBTU]/4-dimethylaminopyridine [DMAP] with or without 1-hydroxybenzotriazole [HOBT], pentafluorophenyl [Pfp] esters gave high percentages of
