Stereochemistry of the allylation and crotylation reactions of alpha-methyl-beta-hydroxy aldehydes with allyl- and crotyltrifluorosilanes. Synthesis of anti,anti-dipropionate stereotriads and stereodivergent pathways for the reactions with 2,3-anti- and 2,3-syn-alpha-methyl-beta-hydroxy aldehydes

Research has been conducted on anti,anti-dipropionate stereotriads. The stereoselective synthetic method for preparation of these compounds has been developed via the reaction of alpha-methyl-beta-hydroxy aldehydes with (Z)-crotyltrifluorosilanes, and the details are reported.
