The crystal structure of the stable isomer of α-benzamidocinnamic acid: the influence of cis–trans-isomerism on the kinetics of the hydrolysis of the products of interaction of α-chymotrypsin with the isomeric 4-benzylidene-2-phenyl-Δ2-oxazolin-5-ones

Abstract

Summary X-Ray analysis of the stable isomer of α-benzamidocinnamic acid has shown it to have the trans-configuration, a result which contradicts most previous assignments of configuration and which bears upon the properties of the products of reaction of α-chymotrypsin with the isomeric 4-benzylidene-2-phenyl-Δ²-oxazolin-5-ones.
