Abstract:

Abstract A three-stage method was proposed for the synthesis of (1S)-(+)-camphor-10-sulfonic acid, (+)-ketopinic and (–)-camphanic acids esters containing a saturated nitrogen-containing heterocycle. It was found that (1S)-(+)-camphor-10-sulfonic acid esters undergo destruction with elimination of the sulfonic acid group in substitution reactions involving nitrogen-containing heterocycles. Esters of (+)-ketopinic and (–)-camphanic acids were formed during the proposed synthetic route, but undergo transesterification under column chromatography conditions. Quantum chemical calculations showed that the destruction of the ester bond in the case of (+)-ketopinic and (–)-camphanic acids requires less energy than the breaking of a similar bond in (–)-borneol esters. It was revealed that the internal bond strength index (IBSI) for the alkyl C–O bond in (–)-borneol esters is higher than in (+)-ketopinic and (–)-camphanic acid esters. Antiviral properties against the H1N1 influenza virus were studied for derivatives of (+)-ketopinic and (–)-camphanic acids.

Abstract:

Natural compounds are the prominent sources for the synthesis of abundant biologically active substances in medicinal chemistry. Camphor exists in two enantiomeric forms i.e., R and S, or both, which are readily obtainable. Camphor is a small molecule with chirality property that binds to some active site, together with its low cost and convenience to transform into synthetically useful derivatives and one of the most important monoterpenoids widely spread in plants and has been used as starting material for the various camphor based derivatives which exhibit several biological activities include antimicrobial, antiviral, antioxidant, analgesic and anti-cancer. Many of those simple derivatives are commercially available in the form of camphor sulfonic acid or ketopinic acid that can be easily be produced from camphor. This compound is primarily used as a chiral starting material in the enantiospecific synthesis of natural products is because of its available methods for the direct or indirect introduction of functionality at C-3, C-5, C-8, C-9, and C-10 carbon atoms. In this study, heterocyclic compounds derived from camphor are arranged in different groups as Camphor-Derived Simple Heterocycles, Fused Camphor-Derived Heterocycles, Spiro Camphor-Derived Heterocycles, Ring Expanded Camphor-Derived Heterocycles and Camphor derived metal complexes. This study summarizes the transformations of camphor and its derivatives along with their biological activities.

Abstract:

New 1-[(1,3-thiazol-2-ylamino)methyl]-2-naphthols were obtained by condensation of 2-aminothiazole, aromatic aldehydes, and 2-naphthol in the presence of (+)-camphor-10-sulfonic acid ((+)-CSA) as an effective catalyst under ultrasound-promoted solvent-free conditions. The 1-[(1,3-thiazol-2-ylamino)methyl]-2-naphthol derivatives were converted in ring-closure reaction with formaldehyde to the corresponding naphthoxazine derivatives.

Abstract:

New polycyclic-fused isoxazolo[4,5-e]pyridines and spirooxindoles were obtained via multicomponent reaction of 5-amino-3-methylisoxazole, indan-1,3-dione, and aromatic aldehydes and reaction of 5-amino-3-methylisoxazole, isatin, and β-diketones in the presence of (±)-camphor-10-sulfonic acid as an effective and nontoxic organocatalyst under ultrasound-promoted conditions. The antioxidant activity of the novel synthesized compounds was studied.
