Optically pure trans-cyclobutane analogues of glutamic acid are prepared by highly selective enzymatic transamination of a single racemic trans-cyclobutane α-ketoglutaric acid derivative 5, which is synthesized in five steps from maleic anhydride. (2S,1′R,2′R)- and (2S,1′S,2′S)-2- (2′-carboxycyclobutyl)glycines L-CBG-II and L-CBG-I are obtained using aspartate aminotransferase (AAT) and branched chain aminotransferase (BCAT), respectively.
