Acetalisation of p-anisaldehyde by either (R) or (S)-butanetriol has been shown to occur selectively and quantitatively by using Noyori's protocol. The crystalline dioxane derivatives R-6a and S-6a which formed respectively in these conditions have been converted efficiently into the title fragments of spiramycin.
