Back Cover: Gold-Catalyzed [2+2+1] Cycloaddition of 1,6-Diyne Carbonates and Esters with Aldehydes to 4-(Cyclohexa-1,3-dienyl)-1,3-dioxolanes (Chem. Eur. J. 3/2014).

- Abstract
The concept of forming a gold carbenoid species in situ from a gold carbenoid species that in itself was generated as a result of [2,3] ‐ sigmatropic rearrangement of a propargylic carbonate or ester is rare in gold catalysis. In this work, such putative organogold intermediates, afforded by AuI ‐ catalyzed cycloisomerization of 1,6 ‐ diyne carbonates and esters, were found to undergo [2+2+1] cycloaddition with aldehydes. The cascade process provided a convenient and expedient one ‐ step synthetic route to 4 ‐ (cyclohexa ‐ 1,3 ‐ dienyl) ‐ 1,3 ‐ dioxolanes in good to excellent yields at catalyst loadings as low as 1 mol %.
