H. Pellissier et al., PREPARATION OF TERTIARY ALCOHOLS AND GAMMA-LACTONES FROM ALLYLSILANESAND ANHYDRIDES, Bulletin de la Societe chimique de France, 132(5-6), 1995, pp. 637-641
The TiCl4-mediated reaction of allyltrimethylsilane and anhydrides yie
lds alkyldiallylcarbinols. In the case of the diallylsilane 1,8-bis(tr
imethylsilyl)octa-2,6-diene and cyclic anhydrides, spiro-lactones resu
lting from a gem-diallylation are obtained with high stereoselectivity
