I found the field of Chemistry very interesting. Saw the article Reaction of enamines with semicarbazone-based amidoalkylating reagents: A straightforward synthesis of annulated 1-aminopyrimidin-2-one derivatives published in 2021.0. Quality Control of 4-Methoxybenzaldehyde, Reprint Addresses Shutalev, AD (corresponding author), Russian Acad Sci, ND Zelinsky Inst Organ Chem, 47 Leninsky Ave, Moscow 119991, Russia.. The CAS is 123-11-5. Through research, I have a further understanding and discovery of 4-Methoxybenzaldehyde
An efficient synthesis of 1-arylideneamino-substituted hexahydro-1H-cyclopenta[d]pyrimidin-2-ones and octahydroquinazolin-2-ones has been developed. The synthesis involves a stereo- and regioselective cascade reaction of the corresponding 4-(tosylmethyl)semicarbazones with 1-morpholinocyclopentene or 1-morpholinocyclohexene to give predominantly bicyclic pyrimidines with an exocyclic C=C double bond (80-97%). The later undergo rapid isomerization when heated in THF in the presence of TsOH to form bicyclic pyrimidines with a significant predominance of those with an endocyclic C=C double bond (90-97%).
