Directed ortho-metalation-nucleophilic acyl substitution strategies in deep eutectic solvents: the organolithium base dictates the chemoselectivity. Chem Commun (Camb) 2019; 55:7741-7744.

Abstract
Directed ortho metalation (DoM) or nucleophilic acyl substitution (SNAc) can be efficiently programmed on the same aromatic carboxylic acid amide, in a choline chloride-based eutectic mixture, by simply switching the nature of the organolithium reagent. Telescoped, one-pot ortho-lithiation/Suzuki-Miyaura cross-couplings have also been demonstrated for the first time in Deep Eutectic Solvents.

Abstract
Multi-substituted 4-aminopyrimidines were prepared from commercially-available benzonitriles and aliphatic amides in transition-metal-free conditions. With KOtBu as the only promoter, target pyrimidines were isolated in moderate to excellent yields.

Abstract
The aim of this review is to present the latest developments in the stereoselective synthesis of conjugated dienes, covering the period 2005-2010. Since the use of this class of compounds is linked to the nature of their appendages (aryls, alkyls, electron-withdrawing, and heterosubstituted groups), the review has been categorized accordingly and illustrates the most representative strategies and mechanisms to access these targets.

Abstract
A stereoselective approach to the synthesis of (E)-alkoxydienylamines (2) is described, starting from alpha,beta-unsaturated acetals (1) and aryl imines, under superbasic conditions. These can be readily converted into alpha-arylglycine derivatives (3) by mild acidic hydrolysis or, in turn, cyclized under oxidative conditions in the presence of a Pd catalyst to 2,3,4,5-tetrasubstituted pyrroles (4).
