Heck vinylation of tertiary allylicalcohols with iodo-acetal Ic, followed by an acid catalysed acetal hydrolysis-dehydration reaction, furnished isoprenoid aldehydes regioselectively in high yields.
C-5-branched vinyltin acetals 1 and 2 obtained by stannylmetallation of homopropargyl acetals with Bu(3)SnMgMe in the presence of cuprous cyanide have been proved to be efficient storable precursors for the synthesis of terpenoids.
