This group’s recently reported mild zinc-catalyzed enantiospecific sp3−sp3 cross-coupling of lactic acid tert-butylester triflate with Grignard reagents was now applied to an iterative approach in the synthesis of a series of all four possible diastereomers of the shown trideoxypropionate. Oligodeoxypropionate structures are a common motif in a large number of biologically relevant natural products
