Shouldn't the pyran ring contain one double bond? Otherwise the phenol group would not be co-planar with the chromene, right?
Yes. You are right! The name was wrong not the structure and I fixed it. The backbone is called 3,4-dihydro-2H-1-benzopyran. Chromane is not recommended. See http://old.iupac.org/reports/provisional/abstract04/BB-prs310305/CompleteDraft.pdf. --kupirijo (talk) 11:18, 21 March 2011 (UTC)
