WebApr 1, 2024 · Abstract A novel synthetic route to CSF1R inhibitor pexidartinib was designed and demonstrated. Crucial to the successful synthesis is a tandem Tsuji–Trost reaction and Heck coupling in combination with palladium and silver catalysis. The final product was obtained via five steps in 49% yield with purity as high as 99.2%. The cheap and available … WebHere we can see why this addition is called 1,4. The nucleophile bonds to the carbon in the one position and the hydrogen adds to the oxygen in the four position. Enolates undergo 1,4 addition to α, β-unsaturated carbonyl compounds is a process called a Michael addition. The reaction is named after American chemist Arthur Michael (1853-1942).
