    • 4. Evaporation of the solvent under reduced pressure gave almost pure product. Further purification was achieved by column chromatography on silica gel or recrystallization from an appropriate solvent to give the desired product(s) in good to excellent yield(s) (Table 1). Most of the products are known and gave satisfactory physical data compared with those of authentic samples.
