A direct synthetic approach to novel quadrupolar [14] azolophanes
摘要:
A convergent '3+1' synthesis allowed a simple entrance to the first examples of [l(4)]metaazolophanes 1 and [l(4)](meta-ortho)(2)azolophanes 2 built up from heterocyclic betaine subunits, illustrating a prototype of phanes constructed by both highly pi-excessive and highly pi-deficient heteroaromatic moieties linked in a 1,3-alternating fashion.
