Alcohols Q 0230Lithium Butylchalcogenolate Induced Michael-Aldol Tandem Sequence: Easy and Rapid Access to Highly Functionalized Organochalcogenides and Unsaturated Compounds. -Butylchalcogenolates, generated in situ, react with alkenes and aldehydes to give the corresponding aldol adducts. An oxidation/elimination sequence allows the conversion into unsaturated compound [cf. (X)]. -(KEPPLER, A. F.; GARIANI, R. A.; LOPES, D. G.; COMASSETO*, J.
