Abstract:

We have already demonstrated that the reactions of 2,2-bis-allyl cycloheptenones with Pd and Ru catalysts lead to intriguing internal tris-ketal molecules such as 4. We have now extended our studies to include the related bis-propargyl derivatives (1-3), with the use of gold catalysts, with and without silver compounds as co-catalysts.
