The asymmetric unit of the title hemisolvate, C28H39N3O4·0.5CH2Cl2 contains two isophthalamide camphor derivatives and one dichloromethane solvent molecule. In the crystal, the chiral molecules are connected into [100] stacks by N—H...O and C—H.

The design and synthesis of a few simple N -benzyl derivatives of isobornyl amine is presented. The derivatives have been assessed as chiral solvating agents for effective discrimination of the signals of some acids in NMR analysis. The single crysta

A series of exo N-((1R,2R,4R)-1,7,7-trimethylbicyclo[2.2.1]heptan-2-yl)benzamides were prepared from (R)-isobornyl amine and screened as chiral solvating agents to discriminate the isomers of 1,1′-binaphthyl-2,2′-diyl hydrogenphosphates by 31P NM

The bromination of camphor has been carried out on a multi-gram scale by a mixture of KBr and KBrO3 in the presence of acid or with HBr/NaBr - H+ and H2O2/oxone® as the oxidant. The 3-bromocamphor is then efficiently converted to camphorquinone by a
