Exploring Mesoionic Imine‐Carbodiimde (MII‐CDI) Adducts: 1,3 H‐Shift, N(I) Compounds and Guanidinate‐Type Ligands

Angewandte Chemie International Edition, Accepted Article.
In this study, we report our recent findings on the synthesis and reactivity of a novel 1,2,3‐triazolin‐5‐imine type mesoionic imine‐carbodiimide (MII‐CDI) adduct. Unlike reported NHC‐CDI adducts, formed by the reactions of N‐heterocyclic carbene (NHC) with CDI, these zwitterionic compounds undergo a spontaneous 1,3 H‐shift, resulting in guanidine‐type

Mechanochemical Strategies Applied to the Late‐Stage Modifications of Pharmaceutically Active Compounds

Angewandte Chemie International Edition, Accepted Article.
This review explores the potential of mechanochemistry in the late‐stage modification of active pharmaceutical ingredients (APIs), offering a comprehensive analysis of methods designed to transform structurally complex molecular scaffolds. By examining the scope, efficiency, and mechanistic aspects of these approaches, the review highlights protocols ...

Step Test for Rapid Screening of Material and Process Parameters for Resin Development in DLP 3D Printing

Angewandte Chemie International Edition, EarlyView.
We present an efficient and rapid step test for determining optimum printing parameters in digital light processing (DLP). It enables the testing of 24 printing parameter settings within one print, is easy to implement, and adaptable to other UV polymerization‐based printing methods, thus speeding up the time from resin screening to optimal printing ...
