A new C(sp3)?H functionalization reaction consisting of the oxidative α-allylation of allyl- and benzyl- methyl ethers has been developed. The C?C coupling could be carried out under mild conditions thanks to the use of cheap and green oxoammonium salts. The scope of the reaction was studied over 27 examples, considering the nature of the substituents on the two coupling partners.
Enantioselective Prevost and Woodward reactions using chiral hypervalent iodine(iii): Switchover of stereochemical course of an optically active 1,3-dioxolan-2-yl cation

supporting information; experimental part, p. 3983 - 3985 (2011/05/04)
Optically active 1,3-dioxolan-2-yl cation intermediates were generated during enantioselective dioxyacetylation of alkene with chiral hypervalent iodine(III). Regioselective attack of a nucleophile toward the intermediate resulted in reversal of enantioselectivity of the dioxyacetylation. The Royal Society of Chemistry.
Gold-catalyzed intermolecular hydroalkoxylation of allenes; difference in mechanism between hydroalkoxylation and hydroamination
Nishina, Naoko,Yamamoto, Yoshinori
, p. 4908 - 4911 (2008/09/21)
A wide range of alcohols 2 react with various allenes 1 in the presence of ClAuPPh3/AgOTf catalyst at ambient temperature without solvent to produce allylic ethers 3. Contrary to the hydroamination, which proceeds through high chiral-face selec
