2,3-cis- and 2,3-trans-N-Arylsulfonyl-2-ethynylaziridines with high enantiomeric purity have been synthesized. N-Protected amino aldehydes synthesized from natural alpha-amino acids were successively treated with Ph3P=C(Br)CO2Me, DIBAL, MsCl-Et3N, NaH in DMSO, and tert-BuOK in THF to yield 2-ethynylaziridines in good to high yields.
