N- [ (9H-Fluoren-9-yl) methoxycarbonyl]-O- (benzyl)-D-serine (0.710 g, 1.70 mmole) in dichloromethane (8 mL) was treated with t-butyl acetate (3 mL) and concentrated sulfuric acid (40 1L) in a sealed flask at 0 °C. Upon completion (TLC), the reaction was quenched with of dichloromethane (10 mL) and saturated aqueous potassium bicarbonate (15 mL).

YieldReaction ConditionsOperation in experiment
Chelmical synthesis: Peptides were synthesized on a Rink amide resin, 0.45 mmol/g [Fmoc-Cys(Trityl)-Wang; Novabiochem, San Diego, Calif.] usinig N-(9-fluorenyl)methoxycarboxyl chemistry and standard side chain protection except on cysteine residues. Cysteine residues were protected in pairs with either S-trityl on the first and third cysteines or S-acetamidomethyl on the second and fourth cysteines. Amino acid derivatives were from Advanced Chemtech (Louisville, Ky.). The peptides were removed from the resin and precipitated, and a two-step oxidation protocol was used to selectively fold the peptides as described previously (Luo et al., 1999). Briefly, the first disulfide bridge was closed by dripping the peptide into an equal volume of 20 mM potassium feliicyanide and 0.1 M Tris, pH 7.5. The solution was allowed to react for 30 min, and the monocyclic peptide was purified by reverse-phase HPLC. Simultaneous removal of the S-acetamidomethyl groups and closure of the second disulfide bridge was carried out by iodine oxidation. The monocyclic peptide and HPLC eluent was dripped into an equal volume of iodine (10 mM) in H20/trifluoroacetic acid/acetonitrile (78:2:20 by volume) and allowed to react for 10 min. The reaction was terminated by the addition of ascorbic acid diluted 20-fold with 0.1percent trifluoroacetic acid and the bicyclic product purified by HPLC. Mass Spectrometry: Measurements were performed at the Salk Institute for Biological Studies (San Diego, Calif.) under the direction of Jean Rivier. Matrix-assisted laser desorption ionization time-of-flight mass spectrometry and liquid secondary ionization mass spectrometry were used.

YieldReaction ConditionsOperation in experiment
79% General procedure: The peptides were synthesized on an activated [44] 2-chlorotrityl chloride resin (1 g) which had been swelled in dry DCM for 30 min. The first Fmoc amino acid (4 equiv) was coupled to the resin manually using dry DCM (10 mL) and DIPEA (6 equiv) for 2 h under a N2 atmosphere. Resin substitution was then determined using the Fmoc UV assay. On 0.1 mM scale subsequent amino acids were also coupled manually using amino acid (0.20 mM, 2.5 mL), DIPEA (1 mM, 1.0 mL) and HBTU (0.50 mM, 1.0 mL) in DMF. The Fmoc group of amino acid was removed using 20percent piperidine?DMF (3 × 10 mL) for 30 min and the next amino acid and sugar amino acid 1a/b were coupled on resin using the same condition. The excess reagents were washed with DMF (2 × 7 mL) and DCM (2 × 7 mL). Cleavage from resin was performed manually, using a cleavage mixture of TFA?DCM [5:95percent (v/v), 3 × 10 mL] for 30 min. The crude compound was then purified using semi-preparative HPLC. All compounds were obtained in good yields.

YieldReaction ConditionsOperation in experiment
48% With 1-hydroxybenzotriazol-hydrate; dicyclohexyl-carbodiimide; In N,N-dimethyl-formamide; at 20℃; for 24h; General procedure: To a stirred solution of the appropriate amino beta-lactam 10 or 11 (4.76 mmol) in anhydrous DMF (30 mL) were added DCC (5.7 mmol), Cbz- or Fmoc-protected l-amino acid (5.7 mmol) and HOBt.H2O (7.3 mmol) at room temperature. After 24 hours, ethyl acetate (50 mL) was added and the mixture was filtered. DMF was removed by washing with water (5 × 50 mL). The organic layer containing the product was reduced in vacuo. The product was isolated by flash column chromatography (dichlormethane: methanol gradient).#10;#10;

YieldReaction ConditionsOperation in experiment
85% With N-ethyl-N,N-diisopropylamine; N-[(dimethylamino)-3-oxo-1H-1,2,3-triazolo[4,5-b]pyridin-1-yl-methylene]-N-methylmethanaminium hexafluorophosphate; In N,N-dimethyl-formamide; at 20℃;Inert atmosphere; Amino acid S30 (27 mg, 0.065 mmol) and S31 (10 mg, 0.0599 mmol) were dissolved in 0.6 mL dry DMF, followed by addition of HATU (30mg, 0.077mmol), DIPEA (25|xL 0.1797 mmol). The resulting mixture was stirred under room temperature overnight and diluted with EtOAc. The solution was washed with 1M HCl and a saturated aqueous NaHCO3 solution. The combined organic phase was dried over Na2SO4 and concentrated, purified by silica gel column to afford compound S32 (27 mg, 85percent).
