I found the field of Chemistry very interesting. Saw the article A green one-pot pseudo-five-component sequential protocol for the synthesis of novel 6,6 ‘-(arylmethylene)bis(benzo[a]phenazin-5-ol) derivatives published in 2021. SDS of cas: 99-61-6, Reprint Addresses Olyaei, A (corresponding author), Payame Noor Univ PNU, Dept Chem, POB 19395-4697, Tehran, Iran.. The CAS is 99-61-6. Through research, I have a further understanding and discovery of 3-Nitrobenzaldehyde
A simple and efficient synthesis of novel 6,6 ‘-(arylmethylene)bis(benzo[a]phenazin-5-ol) derivatives has been developed via a sequential one-pot, two-step, pseudo-five-component tandem reaction starting from 2-hydroxynaphthalene-1,4-dione, o-phenylenediamine, and aromatic aldehydes in the presence of 2-aminopyridine as co-catalyst and p-TsOH as catalyst at 90 degrees C under solvent-free conditions. This sequential green process offers several advantages, such as operational simplicity, high yield, low cost, easy handling, clean reactions, absence of any tedious work-up, and purification of products by non-chromatographic methods.
