Novel spirocyclization based on intramolecular 1,4-addition and its asymmetric version have been developed using a combination of Lewis acid and 1,2-diol. Treatment of five- and six-membered α,β-unsaturated cyclic ketones having a 4-oxopentyl group at the
Usefully Functionalized Products from Conjugate Addition of Sulfur-Stabilized Anions to α-Enones

The addition to α,β-unsaturated ketones of a variety of organolithiums stabilized by at least two phenylthio groups provides mainly the 1,4-addition products at low temperatures in the absence of complexing agents such as HMPA.The products thus generated
