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.

Enantiopure acetamido ketones are converted by an intramolecular Wittig reaction into enantiopure 3-pyrrolines; the product from (S)-serine provides access to novelpolyhydroxylatedpyrrolidines.
A series of unsaturated alpha-amino alcohols were prepared via the allylboration of the corresponding N-protected alpha-amino ketones. The reactions are stereoselective, producing the syn isomers. The diastereoselectivity is not dramatically effected by the electronic nature of the N-protecting group or the reaction temperature but is dependent on the steric requirements of the N-protecting group and the solvent system.
