    • note
    • By carrying out the reaction for time shorter than 6 h, a yield decrease of products 3 and 4 was observed; on the contrary, no yield increase was observed by stirring the reaction mixture for a time longer than 6 h. At 60°C the yields in compounds 4 were lower. At a temperature higher than 120°C, no yield increase in compounds 3 was observed. No coke or tar formation on the calalyst surface was observed by carrying out the reaction at 120°C for 6 h under the reported conditions. A reaction carried out with the used catalyst (previously washed with acetone and heated for 6 h at 500°C) gave a 40% yield of chroman 3a.
