The Dihydroindeno[2,1‐c]fluorene Core: from Syntheses to Properties and Potential Applications

open access: yesEuropean Journal of Organic Chemistry, Accepted Article.
In the last decade, substances possessing the dihydroindeno[2,1‐c]fluorene scaffold showed interesting photo‐physical properties and other potential applications in electronics. The afore‐mentioned compounds belong to the family of five regioisomeric dihydroindenofluorenes, but unlike other ones, they possess angular or, in the case of higher congeners,

Exploring the Impact of Topological Variations on the Stability of the Ground Singlet and Lowest‐Lying Triplet States of Catacondensed Hexabenzenoids

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The influence of topological features on the stability of 37 catacondensed hexabenzenoids in their ground singlet and lowest‐lying triplet states is investigated using a multivariate regression model. This analysis reveals key structural factors governing stability, providing insights into the design of polybenzene‐based materials.

DMAPO/Boc2O‐Mediated One‐Pot Direct N‐Acylation of Sulfoximines with Carboxylic Acids

open access: yesEuropean Journal of Organic Chemistry, Accepted Article.
This report describes a general and simple method for the one‐pot direct N‐acylation of sulfoximines with carboxylic acids using our previously developed 4‐(N,N‐dimethylamino)pyridine N‐oxide (DMAPO)/di‐tert‐butyl dicarbonate (Boc2O) system. The method can be performed under mild low‐temperature reaction conditions and has a wide substrate scope.

5‐Bromo‐8‐Nitro‐1‐Naphthoic Acid as Protective Group for Alcohols Under Mitsunobu Conditions

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Protection of alcohols is carried out using the readily available 5‐bromo‐8‐nitro‐1‐naphthoic acid (NNapOH). Under Mitsunobu conditions, primary and secondary alcohols are converted into the corresponding esters, which are subsequently deprotected under mild reduction conditions. The use of the readily available 5‐bromo‐8‐nitro‐1‐naphthoic acid (NNapOH)

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

open access: yesEuropean 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.

Multistep Reactions Initiated by Amine‐Based Organometallic Methods

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The advent of C–H activation and other organometallic methodologies making use of transient directing groups or free amines themselves for the elaboration of amine substrates provides unique access to cascade‐type reactions that can generate significant molecular complexity in one pot. The pursuit of atom‐ and step‐economical pathways to access complex
