enantioselectivity was also discussed in terms of steric and electronic effects. Coupled with chemical hydrolysis of D-(-)-alpha-phenylglycine amide, biotransformation of DL-phenylglycine nitrile was applied in practical scale to produce both D- and L-phenylglycines in high optical purity.

Nickelperoxide selectively cleaves the α-carbon-nitrogen bond of glycine residues in dipeptide derivatives to give the corresponding amides. The glycine selectivity is attributable to preferential complexation of the reactant residue to nickelperoxide and subsequent reaction via a stable α-centred glycyl radical. The oxidation process serves as a chemical model for peptidylglycine α-amidating monooxygenase

A personal care composition is disclosed comprising a di-amido gellant, wherein the di- amido gellant has a formula (I) wherein R1 and R2 are aminofunctional end-groups which may be the same or different, and L is a linking moiety of molecular weight from 14 to 500 g/mol. The personal care composition may take a variety of forms such as a leave-on composition or an emulsion and/or may comprise one or more actives or agents.
