The non-Kolbe reaction of N-benzoyloxazolidine derivatives 6 derived from l-serine gave optically active N,O-acetals 7 when graphite was used as an anode material. This reaction represents the first example of “memory of chirality” in carbenium ion chemistry. The material used for the anode was critical for the memory of chirality. The substitution of carboxyl group with methoxyl group was found to proceed with an inversion mechanism.
