Deprotective Functionalization: An Emerging Concept for Amine Reactivity

Chemistry – A European Journal, Volume 32, Issue 4, 23 January 2026.
While protecting groups are indispensable in total synthesis to avoid undesired reactivity, installation and removal of protecting groups lead to an increase in the step‐count, cost, waste production and time requirement. One approach tackling these drawbacks is deprotective functionalization, which combines deprotection and postfunctionalization in a ...

On the Nature of Improper Hydrogen Bonding in RCH2F and RCHF2 Motifs

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
The nature of ‘improper’ hydrogen bonds is explored in FnC─H⋯X systems, such as RCF2H interaction with chloride and water. It is noted that increased fluorination decreases the positive charge density on H but increases it on C, thus these interactions are dominated by electrostatic attraction to C over H.

Bioinspired Synthesis of Twin abeo‐Steroids Bufogargarizins A and B via a Divergent Intramolecular Aldol Addition Reaction

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Twin natural products. This manuscript describes a concise biomimetic synthesis of twin abeo‐steroids bufogargarizins A and B with an unusual [7.5.6.5] and [5.7.6.5] skeletons in 19 steps (LLS). The described synthetic approach features the application of a bioinspired regiodivergent intramolecular aldol addition reaction and a selective singlet oxygen‐
