DIVERGENTLY STEREOCONTROLLED REACTION OF AN ALLYLIC SILANE BEARING AN ASYMMETRIC ETHEREAL CARBON TOWARD ALDEHYDES

Article abstract of DOI:10.1016/S0040-4039(00)79929-1

Lewis acid mediated allylation of aldehydes by an allylsilane bearing an asymmetric ethereal functionality proceeded in divergently stereocontrolled manners, i. e., TiCl4 afforded the syn isomer, whereas BF3*OEt2 afforded the anti isomer predominantly.
