Synthesis of N-Substituted Carbonylamino-1,2,3,6-tetrahydropyridines as Potential Anti-Inflammatory Agents
摘要:
Several N-substituted carbonyl/sulfonylamino-1,2,3,6-tetrahydropyridines (5a-i and 9a, b) were synthesized via sodium borohydride reduction of the corresponding N-substitutedimino-pyridinium ylides (4a-i and 8a, b) in absolute ethanol.

Reported herein is a general strategy for the photochemical cross-coupling between N-amidopyridinium salts and various alkyl bro-mides under photocatalyst-free conditions, granting facile access to various C4-alkylated pyridines. This approach exploits the intri-guing photochemical activity of electrondonor-acceptor (EDA) complexes between N-amidopyridinium salts and bromide, which provides a photoactive

In this study, we investigated the untapped potential of β-fragmentation in aminophosphoranyl radicals by leveraging the unique properties of the P–N bond and the substituents of P(III) reagents. Our approach carefully considers factors such as cone angle and electronic properties of phosphine and employs density functional theory (DFT) calculations to probe structural and molecular orbital influence
