Molecular iodine‐mediated functionalization of α‐Carbonyl Sulfoxonium ylides with Thiocyanates, Xanthates and Dithiocarbamates

European Journal of Organic Chemistry, Accepted Article.
In this work, we present a straightforward, rapid, and cost‐effective protocol for synthesizing three distinct classes of α‐functionalized sulfoxonium ylides—α‐xanthate, α‐thiocyanate, and α‐dithiocarbamate—via molecular iodine‐mediated reactions. This method demonstrates broad substrate tolerance, including heterocycles and steroids, delivering 25 ...

Synthesis of 2‐Fluoropyrroles via [4 + 1] Cycloaddition of α,β‐Unsaturated Imines with In Situ‐Generated Difluorocarbene

European Journal of Organic Chemistry, EarlyView.
2‐Fluoropyrroles are synthesized via the [4 + 1] cycloaddition of α,β‐unsaturated imines with difluorocarbene, generated in situ from trimethylsilyl 2,2‐difluoro‐2‐(fluorosulfonyl)acetate (TFDA). The α,β‐unsaturated imines are treated with TFDA in the presence of a Proton Sponge catalyst.

Structural design and property regulation of organic polymers for photocatalytic synthesis of H2O2

InfoScience, EarlyView.
Photocatalytic synthesis of H2O2 offers a sustainable approach. Photocatalytic efficiency depends critically on interfacial electron transfer kinetics and spatial charge separation. Herein, we systematically analyze key factors governing photogenerated carrier dynamics and propose engineered strategies to optimize performance, thereby providing design ...

Solid‐Phase Synthesis of 1,3,5,6‐Tetra‐Substituted 3,5‐Dihydroimidazo[4,5‐c][1,2]Thiazin‐4(1H)‐One 2,2‐Dioxide Derivatives

Journal of Heterocyclic Chemistry, EarlyView.
Through an efficient solid‐phase synthesis method, 32 different 1,3,5,6‐tetra‐substituted 3,5‐dihydroimidazo[4,5‐c][1,2]thiazin‐4(1H)‐one 2,2‐dioxide derivatives were synthesized. The derivative library, with a total of four diversities, showed an overall yield of 7%–32% over 8 steps.

Pd-catalysed heteroarylations of 3-bromochromen-4-one via C-H bond activation of heteroarenes.

, 2013
International audienceThe palladium-catalysed direct coupling of 3-bromochromen-4-one with heteroaromatics was found to proceed in moderate to high yields. A wide variety of heteroaromatics can be coupled with this chomenone derivative using 2 mol % PdCl(
