Zusammenfassung

Two novel compounds, (3S)-2,3-dihydro-3-(4-hydroxyphenyl)-1-benzoxepin-8-ol (1; ruscozepine A) and (3S)-2,3-dihydro-3-(4-hydroxyphenyl)-8-methoxy-1-benzoxepin-7-ol (2; ruscozepine B) were isolated from butcher's broom (Rusci rhizoma) together with a biosynthetically possible phenylethanoid precursor, hydroxytyrosol (3). The structures were elucidated by spectroscopic methods such as 1D- and ...
