leading to the identification of 3 with characteristics that provided for targeted exposure and PK properties in three preclinical species. However, the physical properties of 3 limited plasma exposure at higher doses, both in preclinical studies and in clinical trials as the result of dissolution- and/or solubility-limited absorption, a deficiency addressed by the preparation of the phosphonooxymethyl prodrug

The Heck reaction of (hetero)aryl bromides and acrolein or vinyl ketones using CataCXium® Ptb as a ligand, NaHCO3 as a base, and nBu4NCl provides an efficient access to 3‐(hetero)aryl propenals/propenones, which are directly employed in consecutive multicomponent syntheses of pyrazoles in a one‐pot fashion.
使用CataCXium®Ptb作为配体,NaHCO 3作为碱和n Bu 4 NCl进行(杂)芳基溴化物和丙烯醛或乙烯基酮的Heck反应,可以有效地获得3-(杂)芳基丙烯/丙烯酮。以单罐方式直接用于吡唑的连续多组分合成中。

mechanism. The α-effect increases as the substituent X in the phenyl ring of 2a−f becomes a stronger electron-donating group. However, the magnitude of the α-effect for the reactions of 2a−f is small (e.g., kNhydrazine/kNglycylglycine = 4.6−13) regardless of the electronic nature of the substituent X. The small βnuc has been suggested to be responsible for the small α-effect. A solvent kinetic isotope
