[ 1 ] - Polyvinylpolypyrrolidone supported antimony(III) chloride (PVPP-SbCl3): An efficient catalyst for the synthesis of chromenylphenylpropanones

An efficient synthesis of chromenylphenylpropanone derivatives as warfarine-like analogues was developed by the Michael addition of 4-hydroxycoumarin to α,β-unsaturated compounds in the presence of polyvinylpolypyrrolidone supported antimony(III) chloride (PVPP-SbCl3) as a new polymeric Lewis acid catalyst in chloroform at reflux conditions without formation of 2,4-...
