Multicomponent reaction for the synthesis of 2,3-dihydroquinazolin-4(1H)-ones using isatoic anhydride, aldehydes and NH4OAc under Solvent-free conditions
Quinazolinone derivatives are nowadays well recognized as valuable scaffold in drug discovery. In this manuscript an improved multicomponent process for the chemical synthesis of 2,3-dihydroquinazolin-4(1H)-one derivatives is described. Isatoic anhydride and aromatic aldehydes with ammonium acetate have been subjected to a three-component reaction under solvent-free conditions and catalysis of ...
متن کاملMicrowave-Assisted Synthesis of Novel Functionalized Ketenimines and Azadienes via a Solvent-Free Reaction of Isatoic Anhydride, Alkyl-Isocyanides and Dialkyl Acetylenedicarboxylates
Ketenimines and azadienes are transient intermediates in organic chemistry especially in elimination-addition processes and in the formation of heterocyclic systems. These compounds play a considerable role as intermediates in the synthesis of heterocyclic ring systems. In this present research synthesis of novel ketenimines and azadienes via multicomponent reactions (MCRs...
متن کاملN-Methylimidazole Promotes the Reaction of Homophthalic Anhydride with Imines
The addition of N-methylimidazole (NMI) to the reaction of homophthalic anhydride with imines such as pyridine-3-carboxaldehyde-N-trifluoroethylimine (9) reduces the amount of elimination byproduct and improves the yield of the formal cycloadduct, tetrahydroisoquinolonic carboxylate 10. Carboxanilides of such compounds are of interest as potential antimalarial agents. A mechanism that rationali...
متن کاملReaction of myoglobin with 3,3-tetramethyleneglutaric anhydride.
1. The extent of reaction of the protein with 3,3-tetramethyleneglutaric anhydride was measured by determining the loss of lysine and the equivalent appearance of 3,3-tetramethyleneglutarimidolysine in the hydrolysate at various time-intervals. Of the 19 lysine residues in sperm-whale myoglobin, three did not react with 3,3-tetramethyleneglutaric anhydride. Also, the N-terminal valine did not r...
متن کاملN-Phenylanthranilic anhydride
The complete mol-ecule of the title compound, C(26)H(20)N(2)O(3), is generated by crystallographic twofold symmetry, with the central O atom lying on the rotation axis. The conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond. The dihedral angle between the inner and outer aromatic ring planes is 61.12 (5)°.
