Preparation of (-)-(7R)-7-Acetyl-7-hydroxy-4,4-dimethoxy-5,6,7,8-tetrahydronaphthalen-1(4H)-one, a Chiral AB-Synthon for Anthracycline Synthesis

Warrener, Ronald N.,Gee, Paul S.,Russell, Richard A.

, p. 1100 - 1101 (2007/10/02)

The (-)-(R)-dienone (13) was prepared in 10 steps from the known 8-hydroxy-5-methoxy-2,3-dihydronaphthalen-1(4H)-one (2), and the chirality at C(7) in (13) corresponds to that found at C(9) in the naturally occurring anthracyclines related to daunomycin.
