A variety of α,β-unsaturated carbonyl derivatives gave selective Michael additions with several α-nitrocycloalkanones in water, at room temperature without any added catalyst, or in very dilute, aqueous solutions of potassium carbonate. Both preparative methods constitute new, environmentally benign and more efficient alternatives to previous procedures.

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.
