A convenient and facile stereoselective synthesis of (E)- and (Z)-trisubstituted alkenes has been achieved by treatment of unactivated Baylis-Hillman adducts with NaBH4 in the presence of CuCl 2·2H2O at room temperature for 15 min.

A simple and efficient stereoselective synthesis of (E)- and (Z)-trisubstituted alkenes has been accomplished by treatment of the acetyl derivatives of the Baylis-Hillman adducts with Zn in saturated aq. NH 4C1 solution under reflux. The method has been utilized for the preparation of the two chiral insect pheromones, dominicalure-I and dominicalure-II, of the lesser grain borer Rhyzopertha dominica (F). Copyright

There are described new compounds of formula STR1 in which E is selected from the group consisting of residues of formula STR2 in which R" is selected from the group consisting of amino, vinyl, allyl, ethynyl, C1 -C5 alkyl, C1 -C5 alkoxy, or C1 -C5 alkylthio or a C1 -C5 alkyl group susbstituted by at least one halogen atom; and hydrogen; in which R1 and R2 are each selected from the group consisting of hydrogen, halogen, methyl and ethyl; and R' is selected from substituted phenyl when R" is other than hydrogen, and phenyl, thienyl and substituted phenyl and thienyl when R" is hydrogen. The compounds are useful in the control of parasites. Certain of the compounds have antimicrobial properties.
