Abstract

The title compound was prepared from the N-phthaloyl derivative of the dipeptide glycyl L-methionine by irradiation (300 nm wavelength, 27 hours, 2 mmol in 100 ml of acetone at room temperature). The crude product was purified by column chromatography on silica (methanol/methylene chloride 1:20) which yielded 54% of the diastereoisomerically pure cis compound. The resulting material was dissolved in acetone and after slow evaporation of the solvent, a colorless oil resulted from which tiny and air-sensitive colorless needles crystallized with mp of 468 Κ - 469 Κ.
