Biomimetic synthesis of the flavanone leridol, revision of the structure of the natural product

Solladie, Guy,Gehrold, Nicolai,Maignan, Jean

, p. 2309 - 2314 (2007/10/03)

Two independent syntheses of 5-hydroxy-6-hydroxymethyl-7-methoxy-8- methylflavanone (1), which was supposed to be natural lendol, demonstrated that this structure assignment was wrong and that the natural flavanone lendol was indeed 5-hydroxy-8-hydroxymethyl-7-methoxy-6-methylflavanone (2).
