Abstract |
The PMR 1H spectra of aklavinone, monoanhydroaklavinone and bisanhydroaklavinone were completely assigned with the use of the double resonance technique and the method of resolution enhancement (multiplication of the free induction decay by the Gauss function). It was shown that under mild conditions in the presence of hydrazine, aklavinone dehydrated at the C9-C10 bond and transformed into monoanhydroaklavinone. Under less mild conditions when akalavinone was heated at 250 degrees C, dehydration proceeded at the C9-C10 and C7-C8 bonds to form bisanhydroaklavinone.
