Substitutive Approach Toward Heteroaromatic Amino Alcohols Accessed Through Dioxolanyl Radical Linchpin

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 7, 1 April 2026.
A dioxolanyl linchpin has been used to synthesize aryl ethanolamines from readily available aryl bromide and amine starting materials using a metallaphotoredox/substitution telescoped sequence. This combinatorial approach allows for a wide synthetic scope of both heteroarenes and cyclic amines. Aryl ethanolamines are an important functional group found

Divergent Silylmagnesiation of Ynamides: An Efficient and Versatile Entry to Polysubstituted Enamides

open access: yesChemistryEurope, Volume 4, Issue 4, April 2026.
A set of selective and divergent procedures for the silylmetallation of ynamides is reported. Upon simple reaction with a silyl‐Grignard reagent in the presence of catalytic amounts of copper bromide, a β‐selective, syn‐silylmagnesiation occurs affording a unique and selective access to polysubstituted silylated enamides.

Catalyst‐Free Mass Polymerization and Characterization of Bio‐Polyhydroxhyurethanes Based on Resorcinol Bis(Cyclocarbonate)

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 4, April 2026.
Non‐isocyanate polyhydroxyurethanes (PHUs) were synthesized from resorcinol bis(cyclocarbonate) and eco‐friendly diamines under mild, catalyst‐free conditions. The resulting polymers were extensively characterized for their structural, thermal, and mechanical properties, as well as processability and adhesion performance.
