RING EXPANSION REACTIONS IN THE FORMATION OF MACROCYCLIC LACTAMS. A SYNTHESIS OF DESOXO-INANDENINE

Desoxo-inandenine, a reduction product of the macrocyclic spermidine alkaloids inandenin-12-one and -13-one has been synthesized from 2-nitro-cyclotridecanone by ring expansion reactions including a Zip reaction step.

Synthese von N-(4-Aminobutyl)-16-aza-19-nonadecanlactam und N-(4-Aminobutyl)-17-aza-20-icosanlactam (Desoxoinandenin)

According to Scheme 1, the two homologous macrocyclic spermidine derivatives 12 ad 23 were synthesized.Key steps in both cases were two different types of ring-enlargement reactions.Compound 12 was identical with a degradation product of the naturally occurring spermidine akaloids of inandine-type.
