Steric control in the synthesis of p-benziporphyrins. Formation of a doubly N-confused benzihexaphyrin macrocycle.
The use of 1,4-phenylene-containing tripyrrane analogs provides a general route to expanded p-benziporphyrins. The course of macrocyclization shows a striking dependence on the steric bulk of meso substituents.
