Chiral phosphoric acid-catalyzed enantioselective and diastereoselective spiroketalizations

Catalytic enantioselective and diastereoselective spiroketalizations with BINOL-derived chiral phosphoric acids are reported. The chiral catalyst can override the inherent preference for the formation of thermodynamic spiroketals, and highly selective formation of nonthermodynamic spiroketals could be achieved under the reaction conditions.

Lactones, XX. - Grignardation Followed by Phase-Transfer Oxidation: A Convenient Synthesis of δ,δ-Disubstituted δ-Lactones from δ-Valerolactone

A Grignardation-oxidation sequence, without isolation of intermediates, easily transfers δ-valerolactone (4) into Δ,δ-disubstituted δ-lactones 6.The synthesis of δ,δ-diphenyl-δ-valerolactone (6a) served as an exsample for a detailed investigation of the r
