Article abstract of DOI:10.1248/cpb.48.296

Easily accessible Ac-(Z)-ΔPhe-NHMe was photoisomerized to so far unknown Ac-(E)-ΔPhe-NHMe. Some parameters of the process leading to a diastereomeric mixture of ratio 90(Z): 10(E) have been tested and the photoisomerization has been carried out on a preparative milligram scale. The isomers were separated via crystallization followed by preparative HPLC.
