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 ...

Concise approach for the synthesis of 1,7-dioxaspiro[5.5]undecane, a Dacus oleae pheromone

Results in Chemistry, 2023
A simple and efficient route for the synthesis of 1,7-dioxaspiro[5.5]undecane (Olean), a major component of the male sex attractant of the pheromone blend of the olive fruit fly has been accomplished in six steps starting from 1,4-butanediol. This is the

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 ...

Phosphorus and Glyphosate Adsorption and Desorption Trends across Different Depths in Sandy Soil

Agrochemicals, 2023
The unintended loss of glyphosate and P from cropland may pose an environmental risk to downstream water quality and marine ecosystems. Glyphosate and P compete for exchange sites, and since glyphosate is an organophosphate, it reacts similarly to ...
