Abstract
Nucleoside analogues are effective antiviral agents, and the continuous emergence of pathogenic viruses demands the development of novel and structurally diverse analogues. Here, we present the design and synthesis of novel nucleoside analogues with a carbobicyclic core, which mimics the conformation of natural ribonucleosides. Employing a divergent synthetic route featuring an intermolecular Diels-Alder reaction, we successfully synthesized carbobicyclic nucleoside analogues with high antiviral efficacy against respiratory syncytial virus.

[PMID: 37527973 DOI: 10.1002/chem.202301336] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 07/11/2023] [Accepted: 07/25/2023] [Indexed: 08/03/2023]
Abstract
Regioselective transformations at similar functional groups are of paramount importance in organic synthesis. Traditional strategies towards regioselective functionalization include serial protection/deprotection and sequential synthesis. Modern organic synthesis emphasizes pathway efficiency and protecting group free routes with a goal of exploiting inherent differences in reactivity. This study reports a method for the regioselective functionalization of anilines over aliphatic amines. Utilizing classic conditions for the Baeyer-Mills reaction, anilines were shown to react preferentially in the presence of aliphatic amines. Subsequently, this principle of reactivity was extended to other electrophiles and conditions.
