efficient sequential addition reactions of organolithium and -magnesium reagents to N-thioformyl 2-methoxymethylpyrrolidine have been described. Various combinations of these reagents gives successful results. A highly efficient and diastereoselectiveaddition reaction is also described. Use of the opposite combinations of substituents on organolithium and -magnesium reagents leads to the selective
