mercaptole).Two noteworthy aspects of the synthesis were the highly selective reduction of a bicyclic β-hydroxyketone to afford a diol with the required cis-stereochemistry at the eventual C-7 and C-9 positions of the anthracyclinone and the regioselective hydrolysis of the quinone bisketal to afford the monoketal of proper regiochemistry for the synthesis of( + )-daunomycinone. Thus, ( + )-daunomycinone
