Stepwise Synthesis of Tetrabenzotriazaporphyrins (TBTAPs) and Their Open 2‐ and 3‐Ring Fragments

Chemistry – A European Journal, EarlyView.
Unexpected reaction pathways to porphyrin‐phthalocyanine hybrids are uncovered by the synthesis of “half‐macrocycle” fragments and subsequent macrocyclization. Rather than the expected 2:2 “ABBA” product, the 3:1 “ABBB” hybrid is isolated as the only macrocyclic product.

A Unified Approach for the Synthesis of Conformationally Locked and sp2‐sp3 Fused Hybrids

Chemistry – A European Journal, EarlyView.
This study presents a systematic platform to build rigid sp2–sp3 hybrids via benzyne cycloadditions. Arene‑fused bicyclic oxa‐, aza‐, and carbocycles are converted into medicinally relevant amino acids and applied to Enalapril analogues synthesis. The hybrids combine aromatic interactions with 3D rigidity, tuning lipophilicity, pKa, and solubility ...

Stereochemical Control in the Matteson Reaction

Chemistry – A European Journal, EarlyView.
The Matteson homologation is a highly versatile method for the stereoselective insertion of carbenoids into boronic esters. Through iterative application of the process, complex chiral molecules can be synthesized. The stereoselectivity of the reaction is determined by a chiral diol incorporated in the boronic ester.

Modular One‐Pot Access to π‐Expanded Tetrakis(Phenothiazinyl)‐Silanes With Broadly Tunable Redox and Emission Properties

Chemistry – A European Journal, EarlyView.
A library of 21 tetrakis(phenothiazinyl)‐substituted silanes with broadly variable substituent decoration, which are fully reversible multistage redox systems with intense tunable emission from deep blue to yellow–green (441–533 nm), was rapidly synthesized by bromine–lithium exchange/borylation–Suzuki coupling of tetrakis(4‐bromophenyl)silane or by ...
