K. Masuya et al., 3-(ALKYLTHIO)-1,2-BIS(SILOXY)-3-BUTENES AS EFFICIENT CHIRALITY TRANSFERRED BUILDING-BLOCKS, Tetrahedron letters, 35(43), 1994, pp. 7965-7968
In the presence of Me(2)AlCl, reactions of the title compounds with a
variety of aldehydes proceeded with high efficacy of chirality transfe
r to give the corresponding optically pure ene adducts, which could be
converted to the gamma-lactones, eg., rove beetle pheromone.
