描述Antoine Simonneau‘s thesis highlights the development of new cycloisomerization reactions through the activation of alkynes with gold complexes. First Simonneau describes 1,6-enynes and their direct conversion into allenes through 1,5-hydride or ester migration processes. The author and his team used appropriate propargylic functional groups to achieve this conversion. This study shows that O-tethered 1,6-enynes carrying a strained cycloalkane at the propargylic position could undergo a cyclopropanation/ring expansion cascade reaction. The author employed this rearrangement as the starting point in the design of a new macro cycle synthesis. The next part of the thesis focuses on the cycloisomerization of diynes involving as the first step of the process the rearrangement of one alkyne partner into an allene thanks to a gold-catalyzed 1,3-shift of a propargylic ester. The thesis discloses a new cycloisomerization pattern featuring a 1,5-carbonyl transfer, giving rise to unprecedented cross-conjugated diketones. In the final part of the research, Simmoneau investigates the gold-catalyzed cycloisomerization mechanism of 1,6-enynes and questions the intermediacy of gold acetylides. By

Synthesis of Polyconjugated Bis-Enones Through a Gold-Catalyzed 1,3-Acyloxy Migration-Cyclization-1series of elementary steps to fully rearrange the starting material. Before the results being presented and discussed, we will shortly introduce the reactivities accessible from allenyl esters upon gold catalysis and focus on their use in allenyne-type cycloisomerizations.

https://doi.org/10.1007/978-94-6091-648-9In this chapter we will introduce the reactivity of enynes toward gold catalysis. As many examples of gold-catalyzed enyne cycloisomerizations have been reported in the literature, we will only focus on examples we found relevant in view of the results that will be presented in the following chapters.
