Kinetic and thermodynamic azides from alpha-triflates of gamma-lactones: Intermediates for the incorporation of polyhydroxylated D- and L-alpha-aminoacids into combinatorial libraries
Displacement of α-triflates of 2,3,4-all cis-substituted γ-lactones by sodium azide in DMF gives kinetically an azide with inversion of configuration at the C-2 of the lactone; under the reaction conditions, the initially formed azide epimerises to the apparently more crowded and thermodynamically s...
