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 1b-Ns which, starting from the same precursor, proceeded through 13 steps with a low, decidedly unsatisfactory, overall yield (3%).
