  • Tris(pentafluorophenyl)borane-Catalyzed Alkylation of 1,3-Dicarbonyl Compounds with Benzylic Alcohols: Access to Oxygenated Heterocycles
    作者:Chada Reddy、Jonnalagadda Vijaykumar、René Grée
    DOI:10.1055/s-0030-1258214
    日期:2010.11
    rane has found to be an effective catalyst for the alkylation of 1,3-dicarbonyl compounds using benzylic alcohols as alkylating agents. Various 1,3-dicarbonyl compounds reacted cleanly with different benzylic alcohols to provide the corresponding monoalkylated products in good yield. In addition tris(pentafluorophenyl)borane efficiently promoted the C3 alkylation of 4-hydroxycoumarins. Further, several

    A simple and efficient method has been developed for the synthesis of 4H-chromenes from o-hydroxybenzylic alcohols and dicarbonyl compounds containing active methylene groups by using silica gel supported sodium bisulfate. Various dicarbonyl compounds such as diketones, keto esters, and keto amides can be used in the synthesis of the 4H-chromenes.
