- 論文の詳細を見る
The dimeric compound formed from 3-guaiazulenol has been found to be identical with the main product (<B>Q</B><SUB><B>2</B></SUB>) of the peracid oxidation of guaiazulene, thus the previous structure of <B>Q</B><SUB><B>2</B></SUB> being revised to be a ca. 1:1 mixture of meso (5<I>R</I>,5′<I>S</I>) and two enantiomeric (5<I>R</I>,5′<I>R</I> and 5<I>S</I>,5′<I>S</I>) forms of [5,5′-biguaiazulene]-3,3′(5<I>H</I>,5′<I>H</I>)-dione. Autoxidation of <B>Q</B><SUB><B>2</B></SUB> in pyridine at 25 °C for 1 d mainly gives the title 1,7-azulenedione.
