Abstract

3-(hydroksymetyl)kromen-4-oner av formel (I). og en fremgangsmåte for fremstilling av disse forbindelsene. Fremgangsmåten består i omsetning av forbindelsene av generell formel (II). hvor R er hydrogen, halogen, alkyl med 1 til 4 karbonatomer eller alkoksy med 1 til 4 karbonatomer eventuelt substituert med fenyl eller halogen, med formaldehyd og en basisk katalysator fulgt av dehydratisering i et syremedium til dannelse av 3-(hydroksy-metyl)kromen-4-oner av generell formel (I), hvor R er som definert for (II).
