substituents at the cationic center, with the nucleophile approaching the electrophilic center opposite to R(2). Transition states calculated for the reaction of allyltrimethylsilane with two representative cations support this hypothesis. Tertiary propargylic cations with a stereogenic center (-C*HXR(2)) in the α position were generated by ionization of the respective alcohol precursors with FSO3H in
Diastereofacial selectivity via aldol reactions using ethyl dithioacetate and ethyl dithiopropionate enolates

The lithium enolate of ethyldithioacetate reacts with α-methyl aldehydes to yield the aldol products in which the syn configuration in the positions β and γ to the thiocarbonyl of the product is favored over the anti configuration. This selectivity is solvent-dependent, and is enhanced at lower temperatures. In most cases, syn:anti product ratios obtained under these conditions varied from 57:43 to
