One-pot synthesis of pyrido[2,3-d]pyrimidine derivatives using sulfonic acid functionalized SBA-15 and the study on their antimicrobial activities

الملخص EN

simple and clean one-pot method for the preparation of 7-amino-2,4-dioxo-5-aryl- 1,2,3,4-tetrahydropyrido[2,3-d]pyrimidine-6-carbonitrile derivatives using 6-amino uracil, various aromatic aldehydes and malononitrile in the presence of sulfonic acid functionalized SBA-15 (SBA-Pr-SO3H) is described.

Some of synthesized pyrido[2,3-d]pyrimidines showed antimicrobial activities against some fungi and gram positive and negative bacteria.
