Synthese von Aminocyclopropanen durch redoxneutrale Aminoalkylierung

Angewandte Chemie, EarlyView.
Wir berichten über eine Synthese von Aminocyclopropanen durch Hydroaminoalkylierung unter Einsatz kostengünstiger, leicht zugänglicher Ausgangsmaterialien. Der Ansatz bietet Orthogonalität zu gängigen Methoden und ermöglicht eine breite Toleranz gegenüber funktionellen Gruppen.

Sulfur‐Boron Lewis Pair‐Catalyzed Hydrohalogenation of Alkynes via Formal Hydrogen Atom Transfer

Angewandte Chemie, EarlyView.
A sulfur‐boron Lewis pair enables the stereodivergent hydrohalogenation of alkynes with exclusive Markovnikov selectivity. Mechanistic studies support a proton transfer‐electron transfer (PT‐ET) sequence for vinyl radical formation rather than a concerted hydrogen atom transfer (HAT) pathway.

A Modular Synthesis of C5‐Sulfenyl Thiazoles via an Intermolecular Pummerer Rearrangement: An Underexplored Scaffold for Medicinal Chemistry

Angewandte Chemie, EarlyView.
Modular access to underexplored C5‐sulfenyl thiazoles via an intermolecular Pummerer rearrangement is reported. The methodology exhibits a broad functional group tolerance enabling the seamless design of trisubstituted thiazole cores bearing a sulfur handle for further elaboration.

From Berzelius to Hyperspace: Previously Unrecognized Network of Reactivity in Textbook Brominations

Angewandte Chemie, EarlyView.
Robotic scans across multidimensional condition spaces of classic bromination reactions uncover regions of previously unrecognized reactivity, yielding new major products and novel substitution patterns. Correlation and anticorrelation analyses of product distributions across these hyperspaces enable reconstruction of the underlying mechanistic ...

Dialkyl Ethers and Sacrificial Zinc: Oxide Synthons for Calcium tert‐Butoxide Formation

Angewandte Chemie, EarlyView.
When treated with dialkyl ethers, [(BDI)Ca‐μ‐H‐Zn(t‐Bu)2(η6‐C7H8)] (BDI = HC{C(Me)NDipp}2 initiates a sequence of twofold ether dealkylation and oxide sequestration as tert‐butoxide in a process predicated on a combination of extreme basicity and a cooperative redox process administered by the dissimilar constituent metals.
