The first catalytic asymmetric cross‐dehydrogenative coupling of 2H‐chromenes with aldehydes using o‐chloranil (3,4,5,6‐tetrachloro‐1,2‐ benzoquinone) as an oxidant has been described. The organocatalytic process is tolerated with a broad range of structurally and electronically varied 2H‐chromenes and aldehydes with good yield and high enantiocontrol.
已经描述了使用邻氯苯甲腈(3,4,5,6-四氯-1,2-苯醌)作为氧化剂的2 H-色烯与醛的催化不对称交叉脱氢偶联反应。有机催化过程可耐受各种结构和电子形式的2 H-色烯和醛,具有良好的收率和较高的对映体控制能力。
