Enantiomer stability of atropisomeric 1,5-disubstituted 1,2,3-triazoles
The synthesis and characterisation of axially chiral atropisomeric 1,5-disubstituted 1,2,3-triazoles is reported. Molecules designed to display restricted rotation about 1,2,3-triazole N-1-aryl or 1,2,3-triazole C-5-aryl bonds were investigated by physical and computational techniques. The barrier t...

| Summary: | The synthesis and characterisation of axially chiral atropisomeric 1,5-disubstituted 1,2,3-triazoles is reported. Molecules designed to display restricted rotation about 1,2,3-triazole N-1-aryl or 1,2,3-triazole C-5-aryl bonds were investigated by physical and computational techniques. The barrier to 1,2,3-triazole N-1-aryl rotation was found to be higher than that for 1,2,3-triazole C-5-aryl rotation, confirming axial chirality stemming from restricted rotation about an N-1-aryl bond in a 1,5-disubstituted 1,2,3-triazole to be the most suitable for the development of an axial chirality triazole-based platform. |
