Rewriting Alkene Frameworks: A Practical Strategy for Nitrogen Incorporation

ChemistryEurope, EarlyView.
Morandi and team developed a metal‐free method to insert nitrogen into unactivated alkenes, forming amidines and nitriles via a transient aza‐allenium intermediate. Using mild, open‐flask conditions, the process delivers high yields and broad functional group tolerance.

One‐Step Conversion of Bisphenol A Polycarbonate into Aliphatic Polycarbonate Polyols for Recyclable Polyurethane Production

Chemistry – A European Journal, EarlyView.
One‐step synthesis of aliphatic polycarbonate (APC) polyols via upcycling of bisphenol‐A based polycarbonate (BPA‐PC) is shown. These APC polyols were further utilized to produce thermoplastic polyurethanes that exhibit excellent chemical recyclability, enabling the simultaneous hydrolysis of both carbonate and urethane bonds.

A Scalable L‐α‐Glycerophosphorylcholine Synthesis through the Automatic pH‐Controlled (R)‐Glycidol Ring Opening with Phosphorylcholine

Chemistry–Methods, EarlyView.
Automatic titrator enables the regioselective ring opening of (R)‐glycidol in water in the presence of phosphorylcholine, leading to the synthesis of L‐α‐glycerophosphorylcholine, a commercially available drug, in very high yield. The reaction is triggered by a minimum amount of NaOH and reactants, while the optimal pH is precisely regulated through ...

The [3,3]‐Sigmatropic Allyl Cyanate–Isocyanate Rearrangement on Levoglucosenone Derivatives Stereoselectively Provides 4‐Deoxy‐4‐Aminosugars

Chemistry–Methods, EarlyView.
The Ichikawa rearrangement of allyl cyanates obtained in situ from levoglucosenone‐derived allyl carbamates allows the synthesis of unique 4‐deoxy‐4‐amino‐d‐allose derivatives with complete chirality transfer in a metal‐free three‐step, one‐pot manner.
