A methodology for accessing enantiomerically enriched carbocyclic systems fused to γ-lactones is described. Key steps are the stereoselective synthesis of highly substituted γ-lactones and ring-closing metathesis of the suitable ramifications. The

A set of γ-lactones α,β-fused and β,γ-fused to carbocycles have been synthesized and evaluated for their in vitro antiproliferative activities using the human cancer cell lines SW1573 (lung), T-47D (breast) and WiDr (colon). The compounds are ob

The primary objective in this investigation was to develop a general method to achieve a significant amount of asymmetric induction in the bromonium initiated intramolecular carbocyclization reaction. This goal has been achieved by generation of exoc
