Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 7524-50-7, Name is H-Phe-OMe.HCl. In a document, author is Elmi-Mehr, Maryam, introducing its new discovery. Category: phthalazines.
An efficient and environmentally friendly procedure for the synthesis of 3-amino-1-aryl-5, 10-dioxo-5,10-dihydro-1H-pyrazolo[1,2-b] phthalazine-2-carbonitriles through the one-pot, three-component reaction of phthalhydrazide, an aromatic aldehyde, and malononitrile in the presence of cellulose sulfuric acid (cellulose-SO3H) is described. The reactions occur under thermal solvent-free conditions and the process is operative with various aromatic aldehydes, giving the corresponding products in high yields. Other beneficial features of this protocol include inexpensive, biodegradable and easily obtained catalyst, avoiding the use of harmful organic solvents, simple work-up, and the recyclability and reusability of the catalyst for up to five consecutive runs.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 7524-50-7 help many people in the next few years. Category: phthalazines.
