Abstract
The chiral oxazoline motif is present in many ligands that have been extensively applied in a series of important metal-catalyzed enantioselective reactions. This Review aims to provide a comprehensive overview of the most significant applications of oxazoline-containing ligands reported in the literature starting from 2009 until the end of 2018. The ligands are classified not by the reaction to which their metal complexes have been applied but by the nature of the denticity, chirality, and donor atoms involved. As a result, the continued development of ligand architectural design from mono(oxazolines), to bis(oxazolines), to tris(oxazolines) and tetra(oxazolines) and variations thereof can be more easily monitored by the reader. In addition, the key transition states of selected asymmetric transformations will be given to illustrate the features that give rise to high levels of asymmetric induction. As a further aid to the reader, we summarize the majority of schemes with representative examples that highlight the variation in % yields and % ees for carefully selected substrates. This Review should be of particular interest to the experts in the field but also serve as a useful starting point to new researchers in this area. It is hoped that this Review will stimulate both the development/design of new ligands and their applications in novel metal-catalyzed asymmetric transformations.

Abstract
By taking advantage of benzylidene succinimides as a new class of 3C synthons, a highly diastereo- and enantioselective tandem Mannich reaction/transamidation has been established by reacting them with cyclic trifluoromethyl N-acyl ketimines. Using a Cinchona alkaloid-derived squaramide as the catalyst, the tandem reaction proceeded smoothly under mild conditions and afforded a range of F3C-containing chiral polycyclic dihydroquinazolinones with excellent results (up to 99% yield, all cases >20 : 1 dr, up to 99% ee).

Abstract
In this work, a series of structurally novel benzoxaborole derivatives were designed, synthesized and biologically evaluated as PDE4 inhibitors for battling atopic dermatitis (AD). Among them, the majority exhibited superior PDE4B inhibitory activities to that of the lead compound Crisaborole, an approved PDE4 inhibitor. In particular, 72, the most potent PDE4B inhibitor throughout this series, displayed 136-fold improved enzymatic activity (IC50 = 0.42 nM) as compared to Crisaborole (IC50 = 57.20 nM), along with favorable isoform specificity. In the phorbol ester (PMA)-induced mouse ear oedema model, 72 exerted remarkably greater efficacy than Crisaborole at the same dosage (P < 0.05). Moreover, the ointment of 72 exerted dramatically enhanced therapeutic potency than the ointment of Crisaborole (P < 0.05) in the calcipotriol-induced mouse AD model. In addition to the potent in vitro and in vivo activity, 72 displayed favorable safety in the repeated oral dose toxicity study and did not exhibit phototoxicity. With the above attractive biological performance, 72 is worthy of further functional investigation as a novel anti-AD therapeutic agent.

Abstract
Decarboxylative addition reactions are well known as an effective approach to
C–C bonds formation due to the availability of starting reagents, ease of handling, and low
environmental impact. This approach clearly demonstrated its potential for the synthesis
of the variety of acyclic and heterocyclic compounds, including optically active ones. The
significant amount of articles devoted to this topic published in recent years proves the
importance of this approach in modern organic synthesis. In this review, the recent
achievements in decarboxylative addition to C=C, C=N, and C=O bonds have been summarized
and discussed over the last 6 years.

Abstract
Background: Due to the high reactivity towards various C-nucleophiles, trifluoromethylketimines are known to be useful reagents for the synthesis of α-trifluoromethylated amine derivatives. However, decarboxylative reactions with malonic acid and its mono(thio)esters have been poorly investigated so far despite the potential to become a convenient route to β-trifluoromethyl-β-amino acid derivatives and to their partially saturated heterocyclic analogues. Results: In this paper we show that 4-trifluoromethylpyrimidin-2(1H)-ones, unique heterocyclic ketimines, react with malonic acid under organic base catalysis to regioselectively provide either Michael- or Mannich-type decarboxylative addition products depending on solvent polarity. Malonic mono(thio)esters give exclusively Michael-type products. The two regioisomeric products can be converted into saturated (2-oxohexahydropyrimidin-4-yl)acetic acid derivatives by mild hydrogenation of the endocyclic C=C double bond in the presence of Pd/C as catalyst. The cis-stereoisomers selectively formed upon reduction of the Michael-type products were structurally determined by X-ray diffraction. As a result of this study, a number of novel acetic acid derivatives containing trifluoromethylated, partially or fully saturated 2-oxopyrimidine cores were prepared and characterized as promising building blocks. Conclusions: Regio- and stereoselective protocols have been developed for the synthesis of novel isomeric 4(6)-trifluoromethylated 1,2,3,4-tetrahydro- and perhydro-(2-oxopyrimidin-4-yl)acetic acid derivatives.

Angew Chem Int Ed Engl 2017; 56:12697-12701. [PMID: 28786162 DOI: 10.1002/anie.201706304] [Citation(s) in RCA: 58] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2017] [Revised: 07/17/2017] [Indexed: 01/01/2023]
Abstract
The application potential of primary amine catalysts in the context of Mannich reactions of aldehydes with ketimines is exemplified by isatin-derived ketimines and cyclic trifluoromethyl ketimines. Primary amine catalysts exhibit either unusual stereoselectivity or reactivity, which is not observable with secondary amine catalysts. Moreover, reversal of diastereofacial selectivity between primary and secondary amine catalysts is disclosed. These new reactions provide useful methods for the syntheses of chiral 3-substituted 3-amino-2-oxindoles and dihydroquinazolinones bearing a trifluoromethylated quaternary stereocenter. The synthetic utility of the reactions is demonstrated through the formal synthesis of AG-041R and DPC 083 and the total synthesis of (-)-psychotriasine.
