A Linear Multiporphyrinic [2]-Rotaxane via Amide Bond Formation
摘要:
[GRAPHICS]A linear multiporphyrinic [2]-rotaxane has been synthesized using the transition metal-templating method for threading a gold(III)-incorporating macrocycle onto a rodlike, phenanthroline derived chelate bearing carboxylate end groups. Stoppering has been performed by reacting the resulting prerotaxane with the amino derivative of a zinc tetraarylporphyrin under EDC-HOBt activation. A 34% yield has been realized for this one pot, double amide bond formation.
