Abstract
Methods are provided for preparing all four diastereomers of 2-alkyl-3-hydroxyalkanals, 2-alkyl-3-silyloxyalkanals, and the like, with high enantiocontrol, using non-aldol chemistry. The synthetic methods also provide novel, stereospecific routes to polypropinates and chiral 2-substituted-1,3 diols.
