corresponding β,β′-dialkyl-substituted non-racemic allyl alcohols. In addition, an asymmetric synthesis of such highly substituted allylicalcohols via either enantioselective 1,2-reduction of enones, enzymatic kinetic resolution, or a functionalization of chiral propargyl alcohols, with discussion of scope and limitations of each method is reported.

conclusion is used to explain the apparently anomalous photochemistry of esters 1 and 5 in non-deuterated solvents. The results described also exemplify the use of a base to enhance the efficiency and to alter the direction of deconjugation in the photochemicalconversion of α,β-unsaturated esters to their β,γ-unsaturated isomers.
There are provided two synthetic routes to the known potent anti-leukemic quassinoid bruceantin from the more readily available bruceoside-A and -B. Certain of the intermediate compounds produced in the synthetic sequence as well as bruceantin itself have been shown to possess anti-malarial properties.

A convenient synthesis of α,β-unsaturated imines requiring only an allylic alcohol, an amine and a Ru catalyst has been developed. The use of large excesses of oxidant and the purification of sensitive intermediates can be avoided.
