Modular and Stereoselective Synthesis of Cyclobutane β‐Amino Alcohols

Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.
Late‐stage functionalization and photoisomerization of 1,2‐azaborine leads to a general strategy for the synthesis of diversely substituted cyclobutane β‐amino alcohols. The relative stereochemistry of the resulting products is unambiguously defined by the stereospecific and stereoselective nature of the photoisomerization‐hydrogenation‐oxidation ...

Iron‐Photocatalyzed Alkene Chloroaminoxylation: A Platform for Orthogonally Activatable Building Blocks

Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.
An iron‐photocatalyzed unsymmetrical 1,2‐hetero(atom)difunctionalization of alkenes enables to install orthogonal C–Cl and C–O (alkoxyamine) handles which provides access to diverse nucleophiles via complementary reactivity (SN and photoredox) at two distinct sites. Detailed mechanistic studies elucidate interesting features of the iron catalytic cycle.

The Mechanism of Visible‐Light Photochemical Rearrangements of Conjugated Amide Enolates

Chemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
Visible light irradiation of extended enolates of N‐benzylamides leads to homolytic C─N Bond cleavage, generating a biradical. Computational and mechanistic studies suggest rapid radical recombination within a solvent cage to give either ring‐expanded or rearranged products. ABSTRACT Deprotonation of conjugated amides forms colored solutions of lithium

Unified Approach for the Synthesis of Close Analogues of Reverse‐Prenylated Hexahydropyrrolo Indole Alkaloids

European Journal of Organic Chemistry, Volume 29, Issue 39, 22 October 2026.
A simple, modular, and unified strategy for the synthesis of reverse‐prenylated hexahydropyrrolo indole alkaloids has been developed. An unusual retrosynthetic disconnection allows for the late introduction of a side chain, which distinguishes many members of this class of natural products.
