Mixed metal bases as promoters of 1,4-eliminations

When treated with the LIDAKOR mixture, allyl type ethers very readily undergo 1,4-elimination to afford conjugated dienes (3 - 73). In typical cases, the reaction is brought about stereo- and regioselectively (2 and 7, respectively). Under suitable conditions, lithium dimethylamide or even lithium diisopropylamide adds to the dienes generated in situ thus leading to a variety of new allyl amines (5-8).
A HIGHLY STEREOSELECTIVE SYNTHESIS OF (E)-1- SUBSTITUTED-1,3-DIENES.

(E)-1-substituted-1,3-dienes are obtained with high selectivity by the thermal extrusion of SO2 from 2-substituted-2,5-dihidrothiophene-1,1-dioxides generated by a retro Diels-Alder reaction.An application to the synthesis of (E)-9,11-dodecadien-1-yl acetate, a sex pheromone of the red-bollworm moth is described.
