Kappe, Thomas’s team published research in Synthesis in | CAS: 924-99-2

Kappe, Thomas published the artcileA new modification of the Pechmann reaction, Synthetic Route of 924-99-2, the publication is Synthesis (1981), 524-6, database is CAplus.

Hydroxylated coumarin and quinolinone derivatives I (Z = O, NH, NMe; R = H, Me) reacted with β-oxo esters and NH₄OAc to yield the resp. fused pyrans II [R¹ = H, PhCH₂; R² = Me, H, Ph, CH₂CO₂Et; and R¹R² = (CH₂)₄]. I (Z = NH, R = H) was heated with MeCOCH₂CO₂Et and NH₄OAc at 185° to give II (Z = NH, R = R¹ = H, R² = Me). Some II were also prepared from I and 3-amino-2-alkenoate esters.

Synthesis published new progress about 924-99-2. 924-99-2 belongs to esters-buliding-blocks, auxiliary class Alkenyl,Amine,Aliphatic hydrocarbon chain,Ester, name is Ethyl 3-(dimethylamino)acrylate, and the molecular formula is C7H13NO2, Synthetic Route of 924-99-2.
