A concise preparation of tetrasubstituted hindered functionalized CF3-olefins 2-7 from corresponding enol ether 3 is described. Geometrically pure gamma-CF3,gamma-alkyl allylic alcohol thus prepared could undergo Claisen-type rearrangements and provide, in good yields, carboxylic esters and amides containing a beta- quaternary CF3-substituted carbon.
