F. Fringuelli et al., First efficient regio- and stereoselective metal-catalyzed azidolysis of 2,3-epoxycarboxylic acids in water, SYNLETT, (3), 2000, pp. 311-314
Azidolysis of 2,3-epoxycarboxylic acids occurs quantitatively and with comp
lete regio- and stereoselectivity at C-3 in water as reaction medium in the
presence of a catalytic amount of Cu(NO3)(2).
