one-pot reaction from readily available 2-benzyloxycyclobutanone gave, by means of an asymmetric Strecker synthesis, a kinetic or thermodynamic nitrile with good selectivity. After separation, the major trans-amino nitrile underwent basic hydrolysis and hydrogenolysis, followed by acidic hydrolysis, to give optically active (1R,2R)-1-amino-2-hydroxycyclobutanecarboxylic acid, serinederivative. The absolute
