    • Titanium tetrachloride mediated reaction of crotyltrimethylsilane with propanal produced a mixture of erythro (60%) and threo (40%) isomers. This may be due to the fact that the affinity of Si toward oxygen atoms is higher than that of Sn, and hence that the reaction via Si involves more or less the cyclic transition state. For the affinity of Si and Sn, see: Itoh, K.; Matstjzaki, K.; Ishii, Y.J. Chem. Soc. C 1968, 2709. Itoh, K.; Fukumoto, Y.; Ishii, Y. Tetrahedron Lett. 1968, 3199. The addition of crotyl bromide to aldehydes with chromous ion provides the threo products regardless of the geometry of the starting material: Okude, Y.; Hirano, S.; Hiyama, T.; Nozaki, H.J. Am. Chem. Soc. 1977,99, 3179.

    • Note Added in Proof: In a communication that appeared subsequent to submission of this manuscript. Professor Noyori and co-workers report that an acylic transition state may be involved in the reaction of enol silyl ethers with acetals in the presence of catalytic amounts of Me3SiOTf; We also learned that the similar stereoselection of allylic tin derivatives was observed by Professor Koreeda, University of Michigan, private communication.
