W. Hanefeld et M. Jung, SYNTHESIS OF A RETINOID WITH ACETYLARYLTE TRAHYDRONAPHTHENE STRUCTUREAND AN UNUSUAL CLEAVAGE OF AN ORTHO-ACETYLTRIFLATE, Die Pharmazie, 49(1), 1994, pp. 18-20
During the synthesis of acetyl-substituted retinoids we observed an un
usual bond-cleavage of an ortho-acetyltriflate. The elimination of tri
fluormethansulfinate resulted in the formation of an anellated 1,2-dih
ydrofuran-3-one.
