Dq. Shi et al., A CONVENIENT SYNTHESIS OF -(5,5-DIMETHYL-3-HYDROXY-2-CYCLOHEXENE-1-ONE-2-YL) PROPANIC ESTERS CATALYZED BY KF-ALUMINA, Synthetic communications, 28(17), 1998, pp. 3291-3298
A series of -(5,5-dimethyl-3-hydroxy-2-cyclohexene-1-one-2-yl) propani
c esters were synthesized by reaction of aromatic aldehydes, 5,5-dimet
hyl-1,3-cyclohexanedione and isopropylidene malonate in alcohols catal
yzed by KF-Al2O3. The structure of 4a was determined by X-ray analysis
.
