Microwave-assisted synthesis of the (E)-α-methylalkenoate framework from multifunctionalized allylic phosphonium salts
Meier, Lidiane,Ferreira, Misael,Sa, Marcus M.
experimental part, p. 179 - 186 (2012/07/14)
A convenient and general microwave-assisted method for the synthesis of stereochemically defined α-methylalkenoic acids and esters from allylic phosphonium salts in a basic aqueous medium is described. A selective preparation of acids or esters was dependent on the base (NaOH or NaHCO 3) employed in the reaction and could be achieved with good to excellent yields under mild conditions in the absence of hydrides and reducing agents.

Selective formation of (2E)-2-methylalk-2-enoates or 2-methyl alkanoates could be achieved in moderate to good yields under mild conditions via Sm/HOAc/EtOH system-mediated reduction of Baylis-Hillman acetates depending on the amount of samarium consumed in the reactions.

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
