Regioselective synthesis of bioactive polyheterocycles: Sequential [3, 3] sigmatropic rearrangements of 6-(4-aryloxybut-2-yn-1-yloxy)[1]benzopyran- 2-ones

Article abstract of DOI:10.1080/00397919808004939

7a-Methyl-13,13a-dihydro-7aH-furo[3,2-c : 5,4-f']bis-[1]benzopyran-3- ones (4a-d) are regioselectively synthesised in 65-75% yields by the sequential rearrangements of 6-(4-aryloxybut-2-yn-1-yloxy)[1]benzopyran-2- ones (3a-d) in refluxing N,N-diethylanili
