Abstract:Some 2H-chromen-2-one and imine derivatives have been synthesized through a one-pot condensation of aldehydes, diethyl malonate, and amine compounds. The compounds obtained have been characterized using FTIR, NMR, GC-MS, and elemental analysis. The single-crystal X-ray structure of 3-[piperidine-1-carbonyl]-2H-chromen-2-one (2) has been presented. Compound 2, recrystallized in the monoclinic space C2/c (no. 15), a = 16.654(15) Å, b = 8.789(7) Å, c = 18.460(18) Å, β = 102.89(5)°, V = 2634(4) Å3, Z = 8, T = 296(… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
