The effect of Lewis acids on the pinacol homocoupling reaction of aldehydes promoted by samarium diiodide / R. Annunziata, M. Benaglia, M. Cinquini, L. Raimondi. - In: EUROPEAN JOURNAL OF ORGANIC CHEMISTRY. - ISSN 1434-193X. - 12(1999), pp. 3369-3374.
Abstract:
The effect of various Lewis acids on the samarium diiodide promoted pinacol homocoupling of aldehydes was investigated. The reaction of benzaldehyde proceeded with fair to good 1,2-anti-stereoselectivity, while in the case of other aromatic and aliphatic aldehydes syn-stereoselectivity was generally observed. Chiral alpha-alkylaldehydes allowed for an almost complete stereocontrol favoring syn-1,2-diols.
