The efficient oxidation of benzylic alcohols to carbonyl compounds was performed using chloramine-T and a catalytic amount of indium(III) triflate. The primary benzylic alcohols were converted to the corresponding aldehydes in a good yield, and the s

Monophenyl-substituted dihydropyrazines (Ph-DHP-1 to 4) of 2,3-dihydro-5,6-dimethylpyrazine (Me-DHP-1), which have the inductive effects of apoptosis and mutagenesis, were synthesized and their biological effect was investigated in terms of DNA stran

Dihydropyrazine (DHP), which is produced during the Maillard reaction, generates radicals that not only cause breakage of chromosomal DNA leading to mutagenic lesions but also induce oxidative damage to cellular proteins. In the present study, we sho
