Stereoselective Synthesis of Highly Substituted 1,3‐Dienes via “à la carte” Multifunctionalization of Borylated Dendralenes

چکیده
Despite the high relevance of 1,3-dienes, stereoselective methods to access tetrasubstituted conjugated dienes are still scarce. We here report an efficient and modular approach that provides multifunctional 1,3-dienes with excellent levels regio- stereoselectivity. This methodology is based on a tetracomponent reaction between borylated dendralene, organolithium reagent two different electrophiles. Mechanistic studies reveal this transformation proceeds through carbolithiation/electrophilic trapping in situ formed dendralenic boron-ate complex, followed by stereoretentive halodeborylation. The ease which complex structural can be accessed their synthetic versatility highlight importance utility method.
