Chen, Yixin; Wang, Yurong; Zhong, Rong; Li, Jinshan published the artcile< HFIP Promoted C3 Alkylation of Lawsone and 4-Hydroxycoumarin with Alcohols by Dehydrative Cross-Coupling>, Formula: C19H16O, the main research area is lawsone hydroxycoumarin alc hexafluoroisopropanol dehydrative cross coupling green; alkylated lawsone preparation; functionalized hydroxycoumarin preparation; pyranonaphthoquinone one pot preparation; pyranocoumarin one pot preparation.
An environmentally benign system for the direct alkylation of lawsones and 4-hydroxycoumarins with alcs. in 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) is reported. The reaction proceeded smoothly via a dehydrative cross-coupling process by utilizing the unique properties of HFIP. A variety of alkylated products and subsequent one-pot cyclized products (pyranonaphthoquinones and pyranocoumarins) could be obtained in 40-93% yields.
Journal of Organic Chemistry published new progress about 4-Hydroxycoumarins Role: RCT (Reactant), SPN (Synthetic Preparation), RACT (Reactant or Reagent), PREP (Preparation). 76-84-6 belongs to class alcohols-buliding-blocks, and the molecular formula is C19H16O, Formula: C19H16O.
