N-tert-Butoxycarbonylcarbamates of α-amino acid derivatives underwent asymmetric carbonyl migration by treatment with KHMDS in DMF to give α-amino acid derivatives with an additional ester group at the newly formed tetrasubstituted carbon center in up to 99% ee. Georg Thieme Verlag Stuttgart.

(Chemical Equation Presented) A facile method for N-deallylation at the amide nitrogen of peptides is described. One-pot deallylation of a substrate through ruthenium hydride-catalyzed terminal olefin isomerization and subsequent ozonolysis gave the corresponding deallylated product under mild conditions.
