✦ Synopsis
Sumnary-
The facile pcid-catalyzed racemization of optically active anthracyclinone derivatives((S)(+)-la) was found to proceed through the ring-expanded seven-membered a-hydroxy ketones($ and/or 2 for (S)(+)-1~) by subjecting various plausible intermediates to the racemization condition.
