for preparing lanthionine peptides by a highly chemoselective and stereochemically controlled procedure is presented. It involves an S-alkylation reaction, promoted by activated molecular sieves, on chiral cyclic sulfamidates, both N-protected and unprotected. Of note, the reaction yield was high also for cyclic sulfamidates bearing a free amine group, while other strategies failed to achieve a ring-opening
