Construction of C(sp2)?C(sp3) Bond between Quinoxalin-2(1H)-ones and N-Hydroxyphthalimide Esters via Photocatalytic Decarboxylative Coupling

A novel visible-light-driven decarboxylative coupling of alkyl N-hydroxyphthalimide esters (NHP esters) with quinoxalin-2(1H)-ones has been developed. This C(sp2)?C(sp3) bond-forming transformation exhibits excellent substrate generality with respect to both the coupling partners. Of note, a series of 3-primary alkyl-substituted quinoxalin-2(1H)-ones that were difficult to synthesize by previous methods could be obtained in moderate to excellent yields. Additionally, the mild conditions, easy availability of substrates, wide functional group tolerance and operational simplicity make this protocol practical in the synthesis of 3-alkylated quinoxalin-2(1H)-ones.

Ligand-based design, synthesis, and pharmacological evaluation of 3-methoxyquinoxalin-2-carboxamides as structurally novel serotonin type-3 receptor antagonists

Employing a ligand-based approach, 3-methoxyquinoxalin-2-carboxamides were designed as serotonin type-3 (5-HT3) receptor antagonists and synthesized from the starting material o-phenylenediamine in a sequence of reactions. The structures of the synthesized compounds were confirmed by spectral data. These carboxamides were investigated for their 5-HT3 receptor antagonisms in longitudinal muscle myenteric plexus preparations from guinea-pig ileum against a standard 5-HT3 agonist, 2-methy-5-HT, and their antagonism activities are expressed as pA2 values. Compounds 6a (pA2: 7.2), 6e (pA2: 7.0), 6f (pA2: 7.5), 6g (pA2: 7.5), 6n (pA2: 7.0), and 6o (pA2: 7.2) exhibited antagonism greater than that of the standard 5-HT3 antagonist, ondansetron (pA2: 6.9).
