Molecular‐Scale Tuning of Low‐Molecular‐Weight Gelators Controls Supramolecular Assembly and Directs Human Mesenchymal Stem Cell Growth

Angewandte Chemie, EarlyView.
Chemistry in charge of biology! Simple low‐molecular‐weight gelators, with minor modifications in molecular structure, self‐assemble differently and can also co‐assemble when simultaneously triggered. This creates a family of gels with different properties that direct the growth of stem cells in different ways.

Alkynyltriazenes in Photochemical Metal‐Free Doyle–Kirmse Rearrangements

Angewandte Chemie International Edition, EarlyView.
A metal‐ and additive‐free photocatalytic Doyle–Kirmse reaction of alkynyl triazenes is described, proceeding via cyanocarbene intermediates. This strategy enables the efficient construction of highly substituted asymmetric carbon centers with broad substrate scope, delivering synthetically valuable nitriles.
