Application of 3685-23-2. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: cis-4-Aminocyclohexane carboxylic acid, is researched, Molecular C7H13NO2, CAS is 3685-23-2, about Synthesis of di- and tripeptides containing 4-aminocyclohexanecarboxylic acid.

Amino acid derivatives were coupled to cis- and trans-4-aminocyclohexanecarboxylic acid with diethylphosphoryl cyanide as coupling reagent. Treatment of trans-I (R = Me3CO2C, R1 = OH) with diethylphosphoryl cyanide, followed by condensation with L-valine Me ester gave trans I (R = Me3CO2C, R1 = Val-OMe) (II). Deprotection and coupling of II with N-tert-butoxycarbonyl-L-alanine gave trans-I (R = Me3CO2C-Ala-, R1 = Val-OMe). Similar transformations were effected with cis-I (R = Me3CO2C, R1 = OH). Other coupling procedures investigated were the carbodiimide, p-nitrophenyl active ester, and sym. anhydride methods, which were less satisfactory for coupling to cyclohexane amino acids.
