Simple, Facile, and One-Pot Conversion of the Baylis−Hillman Adducts into Functionalized 1,2,3,4-Tetrahydroacridines and Cyclopenta[b]quinolines
摘要:
A simple, facile, and one-pot synthesis of functionalized 1,2,3,4-tetrahydroacridines and cyclopenta[b]-quinolines from the Baylis-Hillman alcohols, i.e., 2-[hydroxy(2-nitroaryl)methyl]cycloalk-2-enones, is described.

derivatives and relatedcompounds with substituent variations at the 2, 3, and 5--9 positions was prepared and evaluated for antiallergy activity using the rat PCA assay. These compounds were obtained by the condensation of the appropriately substituted 2-aminoquinoline-3-carboxamides with dialkyl oxalates, followed by further chemical transformations. More than two-thirds of the compounds prepared exhibited
Fused heterocyclic ring systems in which a quinoline or a pyridine component is "fused" to a pyrimidine having a 2-methyl, 2-ethyl, or 2-acetyl group and a 4-keto group, and to similar ring systems in which a quinoline, a naphthalene or a pyridine component is "fused" to a pyrimidine having a 2-carboxy group and a 4-keto group, derivatives, and pharmaceutically-acceptable cationic salts thereof, and their use as antiallergy agents, and intermediates therefor.
