Abstract :
[en] This paper surveys recent advances in valorization of transition-metal-catalyzed enyne metathesis as key events in the total synthesis of naturally occurring compounds of biological and medicinal importance. Special attention is devoted to methodologies based on dienyne ring-closing metathesis (RCM) applied in tandem and sequential processes, on relay ring-closing metathesis (RRCM), ring-rearrangement metathesis (RRM), enyne cross-metathesis (CM) and enyne skeletal bond reorganization, all proceeding under metalcarbenes (Ru or Mo alkylidenes) or metal-salts (Pd or Pt) catalysis. The high potential of these procedures in constructing versatile scaffolds as essential structural cores of a diversity of bioactive natural products is highlighted. Inventive functionalizations by non-metathesis transformations intervening in the total synthesis of the targeted natural compounds, prior to (Michael addition, Wittig olefination, allylation etc.) or after (Diels-Alder cycloaddion, Heck and Suzuki-Miyaura reactions, Dess-Martin oxidation, dihydroxylation, epoxidation etc.) the pivotal metathesis step have also been included.
