Versuchsvorschrift
In a manner similar to Example 3, 2.48 g (10 mmol) of 4-(4-hexyloxyphenyl)-butan-2-one was treated with 15 mmol of lithium diisopropylamine, followed by 3 g (12 mmol) of 3-(4-benzyloxyphenyl)-propan-1-al to give, after purification (silica gel dry column, hexane: ethyl acetate, 2:1), 0.7 g of the title compound pound as a pale yellow oil. MS(EI): 488 (m+), 470 (m+ -H2O) Using the method described hereinabove, the following examples further illustrate the invention:
