Quaternary a-amino acids a b s t r a c t Chiral symmetrical alk-2-yne-1,4-diols have been stereoselectively transformed into 5-alkyl-4-alkenyl-4phenyl-1,3-oxazolidin-2-ones, which are precursors of quaternary a-amino b-hydroxy acids. The key step was the cyclization of the bis(tosylcarbamates) of 2-
