Chemistry – A European Journal, EarlyView.The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

Chemistry – A European Journal, EarlyView.Total syntheses of agelamadin F and (±)‐tauroacidin A were achieved by sodium chlorite (NaClO2)‐mediated oxidative C─N coupling. Nine C15–N–amino acid‐substituted oroidin derivatives were successfully prepared to demonstrate the applicability and versatility of this oxidative coupling reaction.

Alkali‐Metal Base Catalyzed Electrocyclization of Isoprene Derivatives
Chemistry – A European Journal, EarlyView.Simple and abundant alkali‐metal base catalysis in combination with Lewis basic polyamines enables the electrocyclization of isoprene‐derived trienes to cycloheptadienes under neat conditions. Mechanistic insight supported by DFT guides a scalable route to seven‐membered carbocycles which, after reduction, give saturated cycloalkanes relevant as ...

N‐Aryl Acridone Derivatives as Effective Catalysts for Energy Transfer Reactions
Chemistry – A European Journal, EarlyView.Acridones derivatives have high triplet energy, are simple accessible, and could be used in challenging [2+2] ENT reactions. ABSTRACT Organic photocatalysts capable of promoting high‐energy triplet energy transfer (EnT) remain limited, particularly for demanding [2+2] photocycloaddition reactions.
