New cyclic peptide assemblies with hydrophobic cavities: The structural and thermodynamic basis of a new class of peptide nanotubes
Amorin, Manuel,Castedo, Luis,Granja, Juan R.
, p. 2844 - 2845 (2003)
A new class of self-assembling peptides based on cyclic peptides made of alternating 3-aminocyclohexanecarboxylic acid (γ-Acc) and α-amino acids is described. The studied cylindrical assemblies are models for a new class of self-assembling peptide nanotub

experimental part, p. 864 - 866 (2010/11/02)
An improved synthesis of (1R,3S)-3-[(tert-butoxycarbonyl)amino] cyclohexanecarboxylic acid from 3-aminobenzoic acid is described utilising milder and more selective conditions. Both a classical salt resolution and an enzymatic approach have been shown to give the desired compound in high selectivity.

Opioid deltorphin C analogues containing cis- or trans-2- or 3- or 4- aminocyclohexanecarboxylic acid residues
Marastoni, Mauro,Guerrini, Remo,Balboni, Gianfranco,Salvadori, Severo,Fantin, Giancarlo,Fogagnolo, Marco,Lazarus, Lawrence H.,Tomatis, Roberto
, p. 6 - 12 (2007/10/03)
The solid phase synthesis, based on the Fmoc chemical protocol, was used to prepare ten deltorphin C (Del-C; H-Tyr-D-Ala-Phe-Asp-Val-Val-Gly-NH2) analogues containing cis- and trans- 2 or 3- or 4- aminocyclohexanecarboxylic acid (ACCA) residues at position 2, ACCA-peptides showed high resistance to degradation by plasma or brain enzymes, negligible affinity for the κ- binding site and modest δ- and/or μ-receptor affinities. Both [cis-3- ACCA2]Del-C analogues and one trans isomer are the only deltorphin analogues of this series exhibiting an appreciable δ-affinity and selectivity. These data suggest that the presence of a conformationally constrained ACCA residue in position 2 of the 'message' sequence of deltorphin C is slightly tolerated.
A mild and facile reduction of azides to amines by N,N-dimethylhydrazine and catalytic ferric chloride
Kamal, Ahmed,Reddy, B. S. Narayan
, p. 593 - 594 (2007/10/03)
Reaction of a variety of azido compounds with N,N-dimethylhydrazine in the presence of a catalytic amount of ferric chloride hexahydrate in methanol results in excellent yields of the corresponding amino compounds. This reductive system is compatible with a wide assortment of functional groups and has also been extended towards the synthesis of pyrrolo[2,1-c][1,4]benzodiazepine antibiotics.
Palladium(0)-Catalyzed Azidation of Allyl Esters. Selective Synthesis of Allyl Azides, Primary Allylamines, and Related Compounds

, p. 3292 - 3303 (2007/10/02)
Palladium(0)-catalyzed reaction of allyl esters such as phosphates, carbonates, and carboxylates with sodium azide gives allyl azides.The azidation proceeds with retention of configuration at the allylic carbon.Optically active (R)-(E)-(+)-4-phenyl-3-buten-2-yl azide (19) is obtained from (R)-(E)-(+)-4-phenyl-3-buten-2-yl acetate (18) stereoselectively.Sequential substitution of (Z)-4-acetoxy-2-buten-1-yl diethyl phosphate (24) with nucleophiles and subsequently azide ion gives (E)-4-substituted-2-buten-1-yl azides 27.The reaction of allyl azides with triphenylphosphine gives iminotriphenylphosphoranes, which are versatile synthetic intermediates of primary allylamines, N-allylamines, and N-allylamides.Treatment of allyl azides with triphenylphosphine and subsequently with aqueous ammonium solution gives primary allylamines.Other synthetic applications of allyl azides are also described.
