One‐pot green synthesis, study of fluorescence properties, and biological activity of pyranochromenes derivatives via mesoporous materials MgO/SBA‐15

This current work describes the preparation of MgO‐SBA‐15 catalysts by ultrasonic method, and it is characterized by the different analysis techniques of XRD, BET, SEM, and IRTF. In order to find out an application for this mesoporous material, MgO/SBA‐15 was used as a heterogeneous catalyst in the one‐pot synthesis of pyrano[3,2‐c]chromenes derivatives isolated at room temperature reaction according to green chemistry criteria. To enhance these derivatives, a spectroscopic study of molecular fluorescence properties was carried out as well as an identification analysis by nuclear magnetic resonance and FTIR was used. Furthermore, biological activity experiment is also carried out, from where the obtained test results were satisfactory for AC09, AC05, and AC10 compounds and they are checked after computation by molecular modeling.
