The present invention provides (i) 6-amino-2,2-dimethyl-3,4,6-trisubstituted
benzopyran derivatives; (ii) a process for synthesizing benzopyran derivatives
with high efficiency by parallel synthesis on a solid-phase as one of combinatorial
chemical synthesis technologies; and (iii) a use of the benzopyran derivatives
for preventing and treating diseases or disorders induced by promotion of lipid
peroxidation or accumulation of oxidized products.
