In an article, author is Tomilov, YV, once mentioned the application of 766-36-9, Name is 3-Ethyl-4-methyl-2,5-dihydro-1H-pyrrol-2-one, molecular formula is C7H11NO, molecular weight is 125.1683, MDL number is MFCD00173861, category is pyrrolines. Now introduce a scientific discovery about this category, Formula: C7H11NO.
Formation of 3-pyrrolin-2-one or imidazolidine derivatives by slow dimerization of N-substituted aziridine-2-carboxylates
Prolonged storage (45-60 days) of N-methyl- or N-cyclopropylaziridine-2-carboxylates leads to their dimerization through the N-C(3) bond cleavage to form 1,3-disubstituted 2-methylimidazolidine-2,4-dicarboxylates in high yields. Prolonged storage of 1-benzylaziridine-2-carboxylate (like the reactions of alkyl pyruvates with primary amines) results in cyclocondensation to yield 3-pyrrolin-2-one derivative.
