Synthesis and Characterization of New Spiroheterocyclic from Isatin and Evaluation of Some Their Antifungal and Antibacterial Activity [PDF]
Spiro compounds Spiro cycles are widely found in natural products, medicines, and functional materials[1] the spiro atom forces the planes of the two rings to almost face one another, spiro compounds are a desirable subclass of heterocyclic scaffolds. In

Structural and stereogenic properties of spiro- and ansa-substituted 1,3-propanedioxy derivatives of a spermine-bridged cyclotriphosphazene [PDF]
Reaction of 1,3-propanediol with the achiral spermine-bridged cyclophosphazene 1 at various molar ratios in THF gives a number of spiro-and ansa-derivatives that exhibit different stereogenic properties, viz. racemic, meso or achiral forms. As expected,

Phenalene-phosphazene complexes: effect of exocyclic charge densities on the cyclotriphosphazene ring system [PDF]
The synthesis and properties of a new series of 1,9-diamino-substituted phenalene complexes of the cyclotriphosphazene ring system is described. One of the compounds is shown to be amphoteric, and this behavior allows an examination of the response of ...

Investigating nano-structuring within imidazolium ionic liquids: A thermodynamic study using photochromic molecular probes [PDF]
Following previous studies involving the thermal relaxation of spirocyclic compounds we extended our studies to investigate the formation of nano-structured domains in ionic liquids (ILs).
