Abstract
The stereochemistry of the new chiral centre C7 in the title galactosyl alp ha -aminoester diastereomer product, C25H37NO7, has been established as S. The pyranose ring has a twist-boat conformation due to the presence of the two isopropylidene ketal moieties. The molecule contains no intramolecular hydrogen bond.
