Resumen

Although the chemoselectivity problems in substitution reactions, which arise from the use of oxygenated nucleophiles in a basic medium by generating anionic species are well-known, we report herein a highly chemoselective ring-opening reaction of hindered cyclic sulfamidates with O-nucleophiles. The reaction occurs with the inversion of configuration at the quaternary centre, allowing the stereoselective synthesis of an important class of β2,2-amino acids, namely O-substituted α-methylisoserines. © 2008 Elsevier Ltd.
