Catalytic Asymmetric Cross‐Dehydrogenative Coupling of 2<i>H</i>‐Chromenes and Aldehydes

Name: Work Video:
Duration: 3 min 30 s
Description: Abstract The first catalytic asymmetric cross‐dehydrogenative coupling of 2 H ‐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 2 H ‐chromenes and aldehydes with good yield and high enantiocontrol.
