The preparation of iminodiacetaldehyde derivatives is reported via oxidative cleavage of 3,4-dihydroxypyrrolidines with sodium periodate. High yields of iminodiacetaldehydes are obtained starting from N-acyl-protected pyrrolidines, whereas the basic N-benzyl-protected derivative does not yield the expected dialdehyde. A cis-configured dihydroxypyrrolidine, prepared from 2,5-dihydropyrrole, reacts considerably
