Chiral Separation of Spiro-compounds and Determination Configuration
Chemical Research in Chinese Universities, 2008Abstract Chiral spirocyclic compounds have attracted the attention of scholars and scientists owing to their potential applications in the pharmaceutical industry as either active pharmaceutical ingredients, catalysts in synthesizing active enantiomers, or as surface modifiers on silica particles to resolve entantiomers.

Polycarbocyclic compounds with separate ring systems, and spiro compounds
1991Publisher Summary This chapter presents an analysis of compounds with rings joined directly or through a carbon chain such as polycyclopropanes and polycyclopropenes. The examples illustrated in this regard include: (1) two directly connected three membered rings, (2) two cyclopropane rings connected by a carbon chain.
