Abstract
Gentle heating of
allyloxyanthraquinones with sodium dithionite in dimethylformamide/water effects
a rapid and controlled rearrangement to give high yields of
2-allylhydroxyanthraquinones.Starting from quinizarin,
key intermediates for two synthetic routes to 4-demethoxydaunomycinone have
been prepared from products by means of two such reductive Claisen
rearrangements.
