The proposed method was operationally simple and to make the process benign for the environment, water used as a reaction medium. No aromatization of dihydropyridinesproducts was done in the presence of TCCA as an oxidant. https://scientiairanica.sharif.edu/article_3985_c2e56f5be982b10cca68fae066e525c0.pdf
