General synthesis for chiral 4-alkyl-4-hydroxycyclohexenones

Hoarau, Christophe,Pettus, Thomas R. R.

, p. 2843 - 2846 (2007/10/03)

Some selective transformations of resorcinol-derived cyclohexadienone are reported. Efforts led to a structure reported to display anticancer properties. On the basis of the results, the structures for natural products reported to contain a 4,6-dihydroxy-4-alkyl-cyclohexenone nucleus are corrected.
