approach for the synthesis of amino-substituted indanes and tetralins from readily available alkyne-derived allylic alcohols via consecutive multibond-forming tandem processes has been developed. In the first one-pot tandem process, a series of cyclic dienes were prepared using an Overman rearrangement under thermal conditions, followed by a ruthenium(II)-catalyzed ring closing enyne metathesis reaction.
已经开发了一种快速且通用的方法,该方法通过连续的多键形成串联方法,从容易获得的炔烃衍生的烯丙基醇中合成氨基取代的茚满和四氢化萘。在第一个单锅串联过程中,在热条件下使用Overman重排制备了一系列环状二烯,然后进行了钌(II)催化的闭环烯炔复分解反应。然后,将得到的外二烯进行第二个一锅串联过程,该过程涉及与炔烃,醌或腈的高度区域选择性Diels-Alder反应,以及随后的氧化步骤,从而得到C-1氨基取代的茚满和四氢化萘的多样化文库总体产量高。
