Abstract:
14-Aryl-14H-dibenzo[a,j]xanthenes and 1,8-dioxo-octahydroxanthenes were synthesized directlyfrom benzyl alcohols via a tandem catalytic process using Choline peroxydisulfate (ChPS). The synthesisproceeds through two steps: an oxidation of the benzyl alcohols to benzaldehydes followed by condensationwith 2-naphthol or dimedone to form products. Choline bisulphate (ChBS) reduced species is generated insitufrom ChPS, which catalyses formation of desired products in shorter reaction time, with good toexcellent yields.
