Zur Kenntnis des dritten ortho‐Oxynaphthaldehyds und der isomeren ß‐Naphthocumarine

Abstract: Von den drei moglichen orthorOxynaphthaldehyden waren bisher CHO @HO C O H A/ OH I1 (/()CHO 111 nur zwei bekannt. der aroxynaphthaldehyd (I) und einer der beiden boxynaphthaldehyde, dem man gemeinhin die Formel I1 zuerkennt, obwohl, wie S i m o n i s in seiner Monographiel) der Cumarine (S. 279) vermerkt, diese Konstitution nicht eindeutig sichergestellt ist. Vor einigen Jahren haben 2 e t z s c h e und Mitarbeitera) versucht, den isomeren koxynaphthaldehyd I11 durch katalytische Reduktion des entsprechenden N… Show more

“…6,7-Benzocoumarin, m.p. 1630 (Boehm & Profft, 1931), was synthesized from 2-hydroxy-3-naphthoic acid via the following intermediates: 2-acetoxy-3-naphthoyl chloride --2-acetoxy-3-naphthaldehyde, followed by a Perkin condensation on this, which afforded the 6,7-benzocoumarin, and recrystallized from benzene. 7,8-Benzocoumarin, m.p.…”
