Reinvestigation of seselin

Reinvestigation of seselin

The crystal structure of seselin (2′,2′‐dimethyl‐3‐pyreno[6,5:7,8]coumarin), C14H12O3, a bioactive pyrenocoumarin, has been reinvestigated. The coumarin ring system is nearly planar and the α‐pyran ring adopts a distorted half‐chair conformation. An inter­molecular C—H⋯O hydrogen bond is observed....
