    • The photodecompositions of both diastereomers of 1 in methanol and acetonitrile were followed by monitoring the decrease of the concentration of 1 by HPLC. The estimated decomposition rates were 180 and 160 nM/s, respectively, for 1-rac in methanol and acetonitrile and 5 and 7 nM/ s, respectively, for 1-meso in methanol and acetonitrile with matched absorbances at 254 nm.
