Bolaamphiphiles
Article Abstract:
Bolaamphiphilic molecules contain a hydrophobic skeleton (one, two or three alkyl chains, a steroid, or a porphrin) and two water-soluble groups on both ends. It is stated that attempts to produce circular conformers by intramolecular interactions between alpha and omega headgroup usually failed if the connecting alkyl chains were long.

Alpha-amido sulfones as stable precursors of reactive N-acylimino derivatives
Article Abstract:
A preparation method for alpha-amido sulfones by a three-components coupling (aldehyde, amide or carbamate, and sulfuric acid or its salt) is described. A growing number of asymmetric catalytic processes using chiral catalysts utilize alpha-amido sulfones as N-acylimino equivalents for the preparation of optically active amines.
