Synthesis of DNA-interactive pyrrolo[2,1-c][1,4]benzodiazepines by employing polymer-supported reagents: Preparation of DC-81

10.1055/s-2004-834821

The research focuses on the synthesis of DNA-interactive pyrrolo[2,1-c][1,4]benzodiazepines, specifically the natural product DC-81, using polymer-supported reagents. This approach aims to create a combinatorial library of substituted pyrrolo[2,1-c][1,4]benzodiazepine derivatives efficiently and without the need for conventional purification techniques like chromatography. The methodology involves an intramolecular aza-Wittig reaction and utilizes reagents such as L-prolinol, 2-azido benzoic acids, borohydride exchange resin, polymer-supported cyclohexylcarbodiimide, polymer-supported sulfoxide, and polymer-supported TPP. The synthesis process includes coupling reactions, oxidation steps using modified Swern procedure and polymer-supported perruthenate, and intramolecular reductive cyclization. The final product, DC-81, is obtained by debenzylation using Pd/C. Throughout the experiments, various analytical techniques such as 1H NMR, MS (EI), and optical rotation measurements were employed to characterize and confirm the structures of the synthesized compounds.

A modular reaction pairing approach to the diversity-oriented synthesis of fused- and bridged-polycyclic sultams

10.1021/ol201962n

The research aims to develop a new method for synthesizing a diverse collection of benzofused sultams, which are cyclic sulfonamides with potential applications in drug discovery. The study employs a reaction pairing strategy involving a triad of reactions: sulfonylation, SNAr addition, and Mitsunobu alkylation. By varying the order of these reactions and using different building blocks such as o-fluorobenzenesulfonyl chlorides, amines, and alcohols, the researchers were able to generate a variety of tricyclic and bicyclic benzofused sultams. Key chemicals used include (S)-prolinol, propargylamine, (R)-(t)-3-hydroxypyrrolidine, and 2-piperidinemethanol. The study concludes that this approach allows for rapid and efficient synthesis of diverse sultam scaffolds in just 2-3 steps, making it highly suitable for high-throughput screening (HTS) in drug discovery. The synthesized compounds were found to be structurally diverse and unique compared to existing analogs, as demonstrated through chemical informatics analysis.
