Budeev, Anton published the artcileUgi reaction-derived 1H-pyrrol-2(5H)-ones proved as valid precursors to a new class of heterocyclic α-diazocarbonyl compounds, Synthetic Route of 6850-57-3, the publication is Tetrahedron Letters (2022), 153598, database is CAplus.
1H-Pyrrol-2(5H)-ones synthesized via a modified literature procedure from primary amines, 3-substituted propiolic acids, isocyanides and glyoxal underwent a facile Regitz diazo transfer to give novel heterocyclic α-diazocarbonyl compounds – polysubstituted diazo pyrrol-2-ones I [R1 = Me, n-Pr, Ph, etc.; R2 = n-Bu, Bn, 3-FC6H4CH2, etc.; R3 = t-Bu, cyclohexyl] .
Tetrahedron Letters published new progress about 6850-57-3. 6850-57-3 belongs to ethers-buliding-blocks, auxiliary class Amine,Benzene,Ether, name is (2-Methoxyphenyl)methanamine, and the molecular formula is C8H11NO, Synthetic Route of 6850-57-3.
