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
据报道,亚氨基二乙醛衍生物的制备是通过3,4-二羟基吡咯烷与高碘酸钠的氧化裂解。从N-酰基保护的吡咯烷开始可得到高产率的亚氨基二乙醛,而碱性的N-苄基保护的衍生物则不能产生预期的二醛。甲顺-型二羟基吡咯烷,由2,5-二氢制备,发生反应以高碘酸钠大大高于相应的反式其在三个步骤从( -型获得的衍生物- [R ,- [R )-酒石酸。 氨基醛-二醇-裂解-氧化
