The racemic title bicycle (V) undergoes spontaneous resolution on crystallization from chloroform or acetone. The absolute configuration of the obtained enantiopure product (16-44% e.e.) is determined by comparison with (S)-(V) derived from (S)-Ser-OMe (I). Mutarotation due to partial conversion of
