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.

A metal‐free approach to meta‐substituted phenols from cyclohex‐2‐enone via catalytic oxidative aromatization has been developed. The transformations are initiated with a catalytic amount of molecular iodine as the direct oxidant, while dimethyl sulfoxide is employed as the terminal oxidant. This practical approach is capable of avoiding the use of metal promoters and costly reagents, the lengthy synthesis
