New methodology for the preparation of N-tosyl aziridine-2-carboxylates

N-Tosyl aziridine-2-carboxylate methyl esters were prepared from methyl N-tosyl-l-serinate or N-tosyl-l-threoninate, tosyl chloride, and K2CO3, under phase-transfer catalysis (PTC) conditions. The same methodology, as applied to the

Synthesis of optically pure 2-Aziridinemethanols: Versatile synthetic building blocks

Synthesis of three cis-trans pairs of N-sulfonylated-2-aziridinemethanols starting from (S)-threonine, (R)-allothreonine, a chiral 2-amino alcohol, or enantiomerically enriched 2,3-epoxy alcohols is described. A synthetic route to N-tosyl- and N-mesyl-2-a
