Design, Synthesis, and Diversification of 3,5-Substituted Enone Library
摘要:
This paper describes the synthesis of a 300 member library of 3,5-substituted enones. The synthesis starts with 6 different bromoenones that are accessed from the corresponding 1,3 diones. These bromides are then diversified by Suzuki coupling with a variety of aromatic and vinyl boronic acids. Additionally a small series of triazoles was synthesized by a Sonogashira coupling reaction dipolar cycloacklition sequence. The library was analyzed by principal component analysis to examine its diversity.

An atom‐ and step‐economic access to an array of unprotected meta‐substituted primary anilines was disclosed using the Semmler–Wolff reaction, promoted by molecular iodine. Therein, noble metal catalysts and inert atmosphere are unnecessary while the forcing reaction conditions and the lengthy synthesis can be avoided. The synthetic utility of this approach is evident in the de novo syntheses of three
