Abstract Stereochemically defined organofluorine compounds are vital to drug discovery and many applicable catalytic strategies have been introduced for accessing these entities stereoselectively. One approach entails incorporation of a fluorine atom (C−F bond formation) or an moiety (e.g., CF 3 2 H), another exploits commercially available with one more atoms. Here, we present the state‐of‐the‐art regarding use alkenyl allylic fluorides in preparation stereochemically fluoro‐organic molecules. Allylic may be purchased generated from acid, carboxylate salt, ester, aldehyde hydrate, ketone bearing several atoms next carbonyl group. We underscore untapped potential purchasable compounds, fluorides, as launching points development stereoselective processes that value therapeutic science.

Pyrazolones and pyrazoles, featuring nitrogen-nitrogen bonds, are two of the most important classes heterocycles, owing to their widespread occurrence in medicinal chemistry functional materials. The last decade has witnessed a rapid increase construction chiral pyrazolone pyrazole derivatives, with application derivatives as powerful synthons. Since our review 2018, large number new achievements emerged this area, requiring timely update. Thus, summarizes these elegant based on multiple reactive sites different In addition, mechanisms interesting biological investigations relating corresponding products also discussed.

This paper presents a new strategy for the construction of chiral 4H-chromene skeleton. A series 2-trifluoromethyl-4-(indol-3-yl)-4H-chromenes were synthesized in moderate to good yields (60-92%) with excellent enantioselectivity (up 97% ee) through palladium-catalyzed asymmetric condensation 2H-chromenes and indoles. These trifluoromethylated, stereochemically rich building blocks hold potential value medicinal chemistry.

Comprehensive Summary The cycloaddition and annulation reactions offer a powerful method toward various important substituted 3,4‐dihydro‐2 H ‐pyran architectures. Nevertheless, the transformation for preparing fused‐polycyclic ones still remains challenging yet highly desirable until now. Herein, we report novel formal [3+3] cascade cyclization reaction to provide lactam‐fused 4‐fluoroalkylated 3,4‐dihydropyran skeletons bearing three contiguous tertiary carbon centers via copper catalysis. Of note, these annulations proceeded in an exclusively diastereoselective manner through successive inert C(sp 2 )‐Cl 3 )‐H functionalization, which exhibited site‐selectivity stereoselectivity. Additionally, evaluations on biological activities of obtained products revealed that several display inhibitory activity against Siha H1975 cancer cell lines.

Abstract A diastereospecific enantiodivergent allylation of pyrazolones is reported which catalyzed by a planar chiral pentaphenylferrocene based palladacycle. With the same catalyst batch both product enantiomers were selectively available. The method applicable to structurally diverse substrates and gave products with enantiomeric excesses between 85 94%. In addition, we could show that are transformable into β‐aminoamides. magnified image

Abstract An efficient strategy for asymmetric trifluoromethylated allylic alkylation of easily available N ‐substituted glycine ethyl esters with α ‐(trifluoromethyl)alkenyl acetates has been developed. Catalyzed by a [Pd(C 3 H 5 )Cl] 2 /( R )‐BINAP, various trifluoromethyl‐containing ester derivatives are afforded good yields and excellent enantioselectivities. The product can be readily converted into diverse fluoro‐substituted species, which shows the practicability this method.
