(2S,4R)-4-Ammonio-5-oxopyrrolidine-2-carboxylate.

ABSTRACT: In the crystal structure of the title compound, C(5)H(8)N(2)O(3), the mol-ecules exist in the zwitterionic form. The pyrrolidine ring adopts an envelope conformation with the unsubstituted endocyclic C atom situated at the flap. The other four endocyclic atoms are coplanar with the exocyclic carbonyl O atom, with an r.m.s. deviation from the mean plane of 0.06?Å. The carboxyl-ate substituent is located axially, while the ammonium group occupies an equatorial position. In the crystal structure, the mol-ecules are linked through N-H?O hydrogen bonds, forming a three-dimensional network.

(2S,4R)-4-Fluoro-pyrrolidinium-2-carboxyl-ate.

Project description:The crystal structure of the title compound, C(5)H(8)FNO(2), at 100 K, displays inter-molecular N-H⋯O hydrogen bonding between the ammonium and carboxyl-ate groups as a result of its zwitterionic nature in the solid state. The five-membered ring adopts an envelope conformation with the C atom at the 3-position as the flap. The compound is of inter-est with respect to the synthesis and structural properties of synthetic collagens. The absolute structure was determined by comparison with the commercially available material.

(1S*,2S*,4R*,5R*)-Cyclo-hexane-1,2,4,5-tetra-carb-oxy-lic acid.

Project description:The title compound, C10H12O8, a prospective raw material for colourless polyimides which are applied to electronic and microelectronic devices, lies about an inversion centre and the cyclo-hexane ring adopts a chair conformation. Two crystallographycally independent carb-oxy-lic acid groups on adjacent C atoms are in equatorial positions, resulting in a mutually trans conformation. In the crystal, O-H?O hydrogen bonds around an inversion centre and a threefold rotoinversion axis, respectively, form an inversion dimer with an R 2 (2)(8) motif and a trimer with an R 3 (3)(12) motif.

(1S,2S,4R)-3,3-Dichloro-4,8,12,12-tetra-methyl-tricyclo-[5.5.0.0]dodeca-6,8-diene.

Project description:The title compound, C(16)H(22)Cl(2), a derivative of β-himachalene, was semi-synthesized from natural essential oils of Cedrus atlantica. The mol-ecule is built up from two fused six- and seven-membered rings. The six-membered ring has a perfect chair conformation, whereas the seven-membered ring displays a screw boat conformation; the dihedral angle between the rings is 46.48 (9)°.

(2S*)-2-Ammonio-3-(1H-indol-3-yl)propionate pyridine-2,4-dicarboxylic acid ethanol solvate.

Project description:In the title compound, C(11)H(12)N(2)O(2)·C(7)H(5)NO(4)·C(2)H(6)O, the (2S*)-2-amino-3-(1H-indol-3-yl)propionic acid is present in the zwitterionic form. In the crystal structure, 2-amino-3-(1H-indol-3-yl)propionic acid mol-ecules and pyridine-2,4-dicarb-oxylic acid mol-ecules are linked through strong inter-molecular O-H⋯O and N-H⋯O hydrogen bonds, forming layers parallel to (100). The layers are linked through the ethanol mol-ecules via somewhat weaker inter-molecular O-H⋯O and N-H⋯O hydrogen bonds, forming thus a three-dimensional network. Weak C-H⋯O and N-H⋯N hydrogen bonding and π-π inter-actions between the aromatic rings are also present.

(2S,3R,4R,5R)-3,4-Dihydr-oxy-5-(hydroxy-meth-yl)pyrrolidine-2-carboxylic acid [(2S,3R,4R,5R)-3,4-dihydr-oxy-5-(hydroxy-meth-yl)proline].

Project description:The crystal structure of the title compound, C(6)H(11)NO(5), establishes the relative configuration at the four stereogenic centres; the absolute configuration is determined by the use of d-glucuronolactone as the starting material for the synthesis. Mol-ecules are linked by inter-molecular O-H?O and N-H?O hydrogen bonds into a three-dimensional network, with each mol-ecule acting as a donor and acceptor for five hydrogen bonds.

(2S,4R)- and (2S,4S)-perfluoro-tert-butyl 4-hydroxyproline: two conformationally distinct proline amino acids for sensitive application in 19F NMR.

Project description:(2S,4R)- and (2S,4S)-perfluoro-tert-butyl 4-hydroxyproline were synthesized (as Fmoc-, Boc-, and free amino acids) in 2-5 steps. The key step of each synthesis was a Mitsunobu reaction with perfluoro-tert-butanol, which incorporated a perfluoro-tert-butyl group, with nine chemically equivalent fluorines. Both amino acids were incorporated in model ?-helical and polyproline helix peptides. Each amino acid exhibited distinct conformational preferences, with (2S,4R)-perfluoro-tert-butyl 4-hydroxyproline promoting polyproline helix. Peptides containing these amino acids were sensitively detected by (19)F NMR, suggesting their use in probes and medicinal chemistry.

Synthesis of N-Fmoc-(2S,3S,4R)-3,4-dimethylglutamine: An application of lanthanide-catalyzed transamidation.

Project description:N-Fmoc-(2S,3S,4R)-3,4-dimethylglutamine (6) was synthesized from tert-butyl N-Boc-(2S,3S,4R)-dimethylpyroglutamate (13). This synthesis involved selective deprotection of a Boc group from a lactam nitrogen in the presence of a tert-butyl ester, Fmoc protection of the lactam, and a lanthanide-catalyzed transamidation reaction of the Fmoc-protected lactam, using ammonia and dimethylaluminum chloride. The scope of Lewis acid-catalyzed transamidation of acylated lactams was explored through the variation of lanthanide, lactam, acyl group, amine, and aluminum reagent. The reactivity of various metal triflates was found to vary in the following qualitative order: Yb approximately Sc > Er approximately Eu approximately Sm > Ce approximately Ag(I) > Cu(II) approximately Zn. Intriguingly, catalysis was only observed when ammonia was the nitrogen nucleophile; addition of other amidoaluminum complexes to acyl lactams was found to be insensitive to the addition of lanthanides.

The synthesis is highly reproducible with good chemical purity, radiochemical yield, and is suitable for translation to cGMP production.
