Alloisoleucine, prepared from a mixture of racemic isoleucine-alloisoleucine diastereoisomers, can be heavily contaminated with isoleucine if the recrystallization of acetyl-dl-alloisoleucine is controlled by melting point only. Two commercial specimens were found to be thus contaminated.

The Preparation of DL-Isoleucine by Asymmetric Transformation
The chemical synthesis of isoleucine leads to a mixture of DL-isoleucine and DL-alloisoleucine. The preparation of DL-isoleucine from the mixture was studied. When the mixture was reacted withExpand
