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.

promoted Michael addition of the substituted acetonitriles to 2-hetaryl-2-(tetrahydro-2-furanyliden)acetonitriles followed by ring transformations has provided novel convenient synthetic methods to nitrogenbridgehead fused cyanopyridines bearing hydroxypropyl side chain. The structures of obtained compounds have been established based on NMR spectroscopy investigation and X-ray diffraction data.
Thiazole derivatives have been made, for example, by reacting a 2-aryl-2,2-dialkoxyethylamine with an appropriately substituted aryl acetyl halide followed by treating the resulting amide with diphosphoryl pentasulfide. The thiazole derivatives are found to be effective immunoregulants.
