Recent Developments for the Ring Opening of Pyrrolidines and Unstrained Cyclic Amines via C−N Bond Cleavage

European Journal of Organic Chemistry, EarlyView.
This review highlights recent advancements in the deconstructive transformation of unstrained cyclic amines, with a particular focus on the C−N bond cleavage of pyrrolidines. Various methodologies, including von Braun‐type, oxidative, and reductive approaches, facilitate the synthesis of diverse amines and the expansion of chemical space.

Recent Advances in the α‐Hydrazination (α‐Amination) of Carbonyl Compounds

European Journal of Organic Chemistry, EarlyView.
In recent years, notable progress has been achieved in the α‐hydrazination (α‐amination) of carbonyl compounds, especially in the direct asymmetric electrophilic α‐hydrazination with dialkyl azodicarboxylates. This review summarizes all the methods that appeared over the past decade, categorized based on the type of the reactive chiral intermediate ...

Benzochalcogenodiazoles, synthesis and applications in medicinal chemistry and photomedicine.

European Journal of Organic Chemistry, Accepted Article.
Benzochalcogenodiazoles BXDs (BOD: benzoxadiazole, BTD: benzothiadiazole, or BSD: benzoselenadiazole) are aromatic bicyclic compounds, containing chalcogen atoms, with applications ranging from material to medicinal chemistry. The recent developments in their preparation and functionalization are taking advantage of new methodologies such as C‐H ...
