A new protocol for the synthesis of d-galactal-derived N-ethoxycarbonyl vinyl aziridine 1β-CO2Et, starting from tri-O-acetyl-d-glucal, is described. The new protocol constitutes a simple and fast access, with a satisfactory overall yield (5 steps, 36%), to a d-galactal-derived vinyl aziridine with a clear improvement compared with the previously described procedure leading to the structurally related N-nosyl aziridine 1β-Ns which, starting from the same precursor, proceeded through 13 steps with a low, decidedly unsatisfactory, overall yield (3%).
