Synthesis and stereochemistry of stereoisomeric 1,3‐benzoxazino‐1,3‐ and ‐3,1‐benzoxazines
, 1991 Partly saturated 3,1-benzoxazino[1,2-c][,3]benzoxazines and 1,3-benzoxazino[3,2-c][1,3]benzoxazines were prepared in one-pot syntheses from different cyclic 1,3-aminoalcohols by treatment with salicylaldehyde or 5-bromosalicylaldehyde, followed by ...

Chiral (Stereoselective) Drugs, Asymmetric Synthesis, and Racemic Resolution Methods
Chirality, Volume 38, Issue 7, July 2026.Chirality is crucial in drug development since both biological targets in the organism and the majority of pharmaceutical compounds are chiral. The synthesis and resolution of chiral compounds are critical steps while developing chiral drugs. Asymmetric synthesis and racemic resolution are the two most common methods for obtaining enantiopure drugs ...

Novel Functional Materials via 3D Printing by Vat Photopolymerization
Advanced Functional Materials, Volume 36, Issue 32, 20 April 2026.This Perspective systematically analyzes strategies for incorporating functionalities into 3D‐printed materials via Vat Photopolymerization (VP). It explores the spectrum of achievable functionalities in recently reported novel materials—such as conductive, energy‐storing, biodegradable, stimuli‐responsive, self‐healing, shape‐memory, biomaterials, and

Concise synthesis and characterization of unsymmetric 1,3-benzoxazines by tandem reactions
Tetrahedron Letters, 2013 Abstract A new synthetic protocol for the preparation of unsymmetric 1,3-bisbenzoxazines using the combination of three-step synthesis and classical one-step benzoxazine synthesis strategies is described. For this purpose, 4-hydroxyphenylaminomethyl phenol (HPAMP) is synthesized as the intermediate and reacted with two different aliphatic amines to ...

Multi‐Scale Structural Insights Into Amphiphilic Model PEG–PCL Co‐Networks From LS and SANS
Macromolecular Chemistry and Physics, Volume 227, Issue 7, 14 April 2026.We present a multiscale structural study of amphiphilic PEG–PCL co‐networks combining light scattering in THF and small‐angle neutron scattering in D2O. This dual‐solvent approach reveals how solvent quality, polymer volume fraction, and PEG/PCL interactions govern static and dynamic correlation lengths, network homogeneity, and nanoscale domain ...
