The synthesis of 2,3-dihydroquinazoline-4(1H)-one and dihydroisoindolo[2,1-a]quinazoline-5,11-dione derivatives in the presence of imidazolium ionic liquid sulfonic acid functionalized SBA-15: a novel feature of SBA-15

One-pot synthesis of tetrahydropyrimido[4,5-b]quinoline derivatives using sulfonic acid functionalized SBA-15 and their antimicrobial activities

A Simple and efficient method for synthesis of tetrahydropyrimido[4,5-b]quinoline derivatives via three component reaction of aromatic aldehydes, dimedone and 6-amino uracil derivatives using a catalytic amount of sulfonic acid functionalized nanoporous silica (SBA-15-Pr-SO3H) is described. The advantages of this method are easy and clean work-up, high yield, mild reaction c...

Synthesis of the biologically active henna based benzochromene derivatives using ionic liquid functionalized SBA-15 as a nanoreactor

SBA-15 was prepared and then functionalized with N-methyl-N’-propyltrimethoxysilyl imidazolium chloride as ionic liquid moiety. The ionic liquid functionalized SBA-15 (SBA-IL) was characterized by different analytical techniques including FT-IR, N2 adsorption-desorption, TGA and SEM image. According to the obtained results it was found that the organic groups were g...
