Coenzyme Q10

Coenzyme Q10 2-[(2E,6E,10E,14E,18E,22E,26E,30E,34E)-3,7,11,15,19,23,27,31,35,39-decamethyltetraconta-2,6,10,14,18,22,26,30,34,38-decaenyl]-5, 6-dimethoxy-3-methylcyclohexa-2,5-diene-1,4-dione Coenzyme Q10 (ubiquinone-10, CoQ10, CoQ, Q10 or simply Q) is aubiquinone containing 10 isoprenoid units. First discovered in 1957 by Crane et al. [1], its chemical structure was determined by Karl Folkers [2], who later won the Priestley medal from the American Chemical Society. This … Continue reading

Luche reduction

Luche reduction is the selective organic reduction of ketones to alcohols with lanthanoid chlorides such as cerium(III chloride andsodium borohydride. The Luche reduction can be conducted chemoselectively toward ketone in the presence of aldehyde or toward α,β-unsaturated ketone in the presence of non-conjugated ketone.1,2,,3 An enone forms an allyl alcohol in a 1,2-addition. Competing conjugate 1,4-addition is suppressed. The solvent is an alcohol such asmethanol or ethanol. The selectivity … Continue reading
