cyclization to construct biaryl lactones has been developed. The synthetic utility of this new reaction was demonstrated in an atom-economical and operationally convenient total synthesis of the natural product cannabinol from commercially available starting materials, with the newly developed method used for two key steps.
已开发出一种实用的Pd(II)/ Pd(IV)催化的羧基定向C–H活化/ C–O环化反应来构建联芳基内酯。该新反应的合成效用在天然经济的大麻素从市售原料中进行了原子经济且操作方便的全合成中得到了证明,其中新开发的方法用于两个关键步骤。
