(HTE) has emerged as an important tool in drug discovery, providing a platform for preparing large compound libraries and enabling swift reaction screening over wide-ranging conditions. Recent advances in automated high-density, material-sparing HTE have necessitated the development of rapid analytics with sensitivity and resolution sufficient to identify products and/or assess reaction performance in

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

Ce procédé consiste à convertir en cinq opérations l'acide 5-oxo-3-phényl-3-cyclohexènecarboxylique en produit désiré. L'invention se rapporte également à des procédés de décomposition de l'acide carboxylique 5-oxo-3-phényl-3-cyclohexène au moyen de la cinchonidine pour obtenir l'acide (S) 5-oxo-3-phényl-3-cyclohexènecarboxylique ou l'$g(a)-chymotrypsine et hydrolyser sélectivement n-butyl 5-oxo-3-phényl-3-cyclohexènecarboxylate de manière à obtenir l'acide (S) 5-oxo-3-phényl-3-cyclohexènecarboxylique, ainsi que d'autres produits intermédiaires de valeur utilisés dans ces procédés.
