The macrocyclic spermidine alkaloid (-)-(S)-neoperiphylline: Revision of the structure based on the total synthesis

The total synthesis of the two isomeric macrocyclic enamides 2 and 17 is described. The precursor 14 was synthesized by means of template-assisted macrocyclization (Scheme 2). Isomerization of 14 in the presence of [Fe(CO)5] gave 2 and 17 (Sche

Synthesis, catalytic activity and redox properties of palladium(0) complexes with 15-membered triolefinic macrocyclic ligands containing one, two or three ferrocenyl groups

A series of 15-membered triolefinic macrocycles containing ferrocenyl groups and their palladium(0) complexes have been synthesized and characterized. Their catalytic activity has been demonstrated in Suzuki-type cross-coupling and in the Heck reaction. Their redox properties have been investigated by means of cyclic voltammetry.

Preparation of nitrogen-containing 15-membered triolefinic macrocycles: (E,E,E)-1,6,11-tris(arylsulfonyl)-1,6,11-triazacyclopentadeca-3,8,13-trienes

Three routes to (E,E,E)-1,6,11-tris(arylsulfonyl)-1,6,11-triazacyclopentadeca-3,8,13-trienes are described. Optimization of the preparation of key intermediates has opened the way to efficient synthesis of a broad variety of 15-membered, nitrogen-containing triolefinic macrocycles.
