The cycloheptanes and cyclooctanes
, 1991 Publisher Summary This chapter discusses cycloheptanes and cyclooctances, which are compounds containing more than seven or eight rings. Many of these compounds have been found to exhibit significant biochemical effects. The chemistry of monocyclic compounds with seven and eight membered rings is investigated in this chapter.

Wacker Oxidation of Trisubstituted Alkenes: Pd(II)-Catalyzed Oxidative Ring Expansion of Exocyclic α,β-Unsaturated Carbonyl to 2-Fluoro-1,3-Dicarbonyl Compounds. [PDF]
Angew Chem Int Ed EnglFirst examples of Pd(II)‐catalyzed Wacker oxidation of trisubstituted alkenes, coupled with electrophilic fluorination, enable a one‐carbon ring expansion of exocyclic α,β‐unsaturated carbonyls to 2‐fluoro‐2‐acyl‐cycloalkanones. Abstract The Wacker oxidation is a powerful synthetic method widely employed for the transformation of monosubstituted ...

Bicyclic Isoxazoline Derivatives: Synthesis and Evaluation of Biological Activity
Molecules, 2022 The application of non-planar scaffolds in drug design allows for the enlargement of the chemical space, and for the construction of molecules that have more effective target–ligand interactions or are less prone to the development of resistance.
