A copper-catalyzed chemodivergent approach to five- and six-membered benzocycles from dienyl arenes tethered with a ketone has been developed. Through proper choice of coordinating ligands and catalytic conditions, copper-catalyzed borylative cyclization of a single dienyl arene can be diverted to two different pathways, leading to indanols and dihydronaphthalenols with high stereoselectivity.

已经开发了一种铜催化化学发散方法,用于从与酮相连的二烯基芳烃制备五元和六元苯并环。Through proper choice of coordinating ligands and catalytic conditions, copper-catalyzed borylative cyclization of a single dienyl arene can be diverted to two different pathways, leading to indanols and dihydronaphthalenols with high stereoselectivity. 手性双齿双膦配体 ( S , S )-Ph-BPE 最适用于通过船状过渡态将铜烯丙基不对称加成到系链酮上,而 NHC 配体导致硼烯丙基加成产生具有高非对映选择性的茚满醇。
