Abstract: In recent years a number of compounds containing bis-spiroacetal systems have been ?. The synthesis of bicyclic molecules containing guanidinium subunits, such as (Scheme 22), are of considerable interest due to the wide range of biological activities presented by this family of natural products (see Section ).In one of the first biomimetic studies toward ptylomycalin A, a series of polycyclic compounds have been prepared through an intermediate 1-imino /bicyclic-molecule.

Thiazole moiety-containing compounds invention present an extensive range of applications in medicinal chemistry such as antibiotics, bacteriostatics, CNS regulants to high selling diuretics [].
