Sequence Control in Sulphur‐Containing Ring‐Opening Co‐ and Terpolymerisations

Angewandte Chemie, EarlyView.
Sulphur‐containing polymers offer unique avenues for degradability, recyclability and optical performance—but their synthesis is often plagued by side reactions. This minireview outlines recent strategies to control or harness O/S scrambling in ring‐opening co‐ and terpolymerisations, enabling precise sequence control.

Advances on Albumin‐Based Carriers for Anticancer Drug Delivery

Advanced NanoBiomed Research, EarlyView.
This study systematically classifies the drug delivery modes of albumin by examining the characteristics of its surface‐active groups and internal binding sites. It provides an in‐depth analysis of various drug delivery strategies and their corresponding targeting mechanisms.

Asymmetric Intramolecular α‐Arylation of Polar Amino Acids Bearing β‐Leaving Groups

Angewandte Chemie, EarlyView.
Use of enolate chemistry to functionalise amino acids with β‐heteroatom side‐chains (serine, cysteine, threonine, etc.) is hampered by β‐elimination. We show that α‐arylation can be achieved by incorporating the side chain into a saturated heterocycle, making the unwanted elimination a disfavoured 5‐endo‐trig reaction.

Eine spannende Reise: Wolfram(VI)‐ und Wolfram(V)‐Fluoride treffen auf N‐Heterocyclische Carbene und cyclische (Alkyl)(Amino)carbene

Angewandte Chemie, EarlyView.
Die ersten Wolfram(VI)‐Fluorido‐Komplexe mit N‐heterocyclischen Carbenen (NHCs) und cyclischen (Alkyl)(Amino)carbenen (cAACs) als Liganden wurden synthetisiert und charakterisiert. Die Reduktion der siebenfach koordinierten Komplexe führte zu seltenen, Lewis‐Basen‐stabilisierten oktaedrischen Wolfram(V)‐Fluorido‐Komplexen, einem dinuklearen, Fluorido ...
