carbanions and ligands on π-allylpalladium has been investigated in the substitution of primary or tertiary terpene derivatives. Conditions have been found under which the substitution takes place essentially at one or the other end of the allylic system. This provides a new and convenient way to obtain compounds with quaternary carbonatoms, which has been exemplified by the synthesis of 3,3-dimethyl-4-pentenenitrile

[3,3] Sigmatropic rearrangement of allylic alcohols with ethyl β,β-dietboxyacrylate provides a convenient method for the regiospecificsynthesis of substituted allylmalonates 3.
A cobalt(I)-catalyzed regioselective allylic alkylation of tertiary allylic carbonates with 1,3-dicarbonyl compounds is described. The alkylated products are obtained in high yields and with excellent selectivity towards the kinetic branched regioisomer. Mechanistic insights by combining experimental and computational investigations support a Co(I)/Co(III) catalytic cycle.
