  • Route to synthetic analogues of Rocaglamide and Aglafoline using cascade transformations initiated by oxy-cope rearrangement of bis-alkynes
    Patent number: 9206100
    Abstract: A method for preparing a cyclobutene compound or a cyclopentenone is provided. The method comprises contacting an ?,?-diketone with a metal acetylide at a temperature below 0° C. to thereby form a reaction mixture comprising a bis-alkyne precursor. The bis-alkyne precursor rearranges into a bis-allenic intermediate, which undergoes further rearrangement into the cyclobutene compound or the cyclopentenone compound as the temperature of the reaction mixture increases from below 0° C. to above 0° C.
    Type: Grant
