✦ Synopsis

Five-coordinate bicycloazastannoxides containing a b-hydroxy-␣-amino acid moiety were synthesized. By hydrolysis under the action of 10% HCl, five b-hydroxy-␣-amino acids were prepared, and their structures were characterized by 1 H NMR spectroscopy, MS, and elemental analyses. The mechanism of the hydrolysis of the organotin (IV) complexes is discussed, and the yields of diastereomers are investigated by the HPLC method. This represents a new method for preparing b-hydroxyl-␣-amino acids.
