Chemoselective Synthesis of α‐Chloro and α,α‐Dichloro Acetamidines via the Carbenoids Addition to Inherently Low Electrophilic Carbodiimides

Advanced Synthesis &Catalysis, EarlyView.
Carbodiimides act as competent electrophilic synthons for the chemoselective addition of lithium mono‐ and di‐halocarbenoids. The transformation is provided through a single synthetic operation—hitherto elusive—halogenated acetamidines. Interestingly, the constitutively tamed electrophilicity of the starting materials is effectively counterbalanced by ...

Solvent‐Free Mechanocatalytic Reduction of Nitro Compounds with Hydrogen Gas and its Application in the Synthesis of Drugs and their Intermediates

Advanced Synthesis &Catalysis, EarlyView.
A solvent‐free mechanochemical reduction of nitro compounds using hydrogen gas is presented. In addition to enabling the synthesis of a variety of functionalized aniline derivatives, the method has been scaled up to gram quantities, evaluated for trace metal impurities, and applied to the synthesis of pharmaceutical compounds and their precursors.

Redrawing the Mannich‐Type Reaction through Carbonyl Umpolung Reactivity

Advanced Synthesis &Catalysis, EarlyView.
GA: Herein, a conceptually novel one‐pot multicomponent strategy is reported for the streamlined construction of five‐membered imidazolidines from 1,2‐diaza‐1,3‐dienes (onefold), amines (twofold), and formaldehyde (twofold). This redesigned Mannich‐type reaction that exploits a carbene‐like activity of 1,2‐diaza‐1,3‐dienes (realized by “umpolung ...

Tunable Preparation of α‐Aminoacyl Fluorides and α‐Fluoroamides via Base‐Induced Cascade Multiple‐Cleavage Processes from Bromodifluorohydrin Reagents and Amines

Advanced Synthesis &Catalysis, EarlyView.
A mild and versatile strategy enabling the divergent synthesis of α‐fluoroamides and α‐aminoacyl fluorides from 2‐bromo‐2,2‐difluoro alcohols and amines is developed. The reaction shows broad scope and operational simplicity. Mechanistic and density functional theory studies support the formation of a putative gem‐difluoroepoxide intermediate ...

Challenges in agrochemicals design [PDF]

Journal of Cheminformatics, 2013
Design of active ingredients is a multidimensional task. Sufficient target activity in combination with high bioavailability and no (or at least low) toxicological behaviour are prerequisites for promising candidates. In this respect, pharmaceutical and agrochemical companies need to address the same issues.

Integrating Visible‐Light Photocatalysis and Enzymes for the Stereoselective Synthesis of Alcohols and Amines

Advanced Synthesis &Catalysis, EarlyView.
The integration between visible‐light photocatalysis and biocatalysis has the potential to greatly improve modern organic synthesis by combining the production of valuable synthetic intermediates under mild photochemical conditions with the high degree of stereoselectivity reached by enzymes. The review collects the recent efforts in the photoenzymatic

Exploring Biophysical Linkages between Coastal Forestry Management Practices and Aquatic Bivalve Contaminant Exposure

Toxics, 2021
Terrestrial land use activities present cross-ecosystem threats to riverine and marine species and processes. Specifically, pesticide runoff can disrupt hormonal, reproductive, and developmental processes in aquatic organisms, yet non-point source ...
