Reaktionsschritte

Following the basic procedure of Example 11(d), by reacting 1.66 g (6.8 mmol) of α-ethynyl-5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthalenemethanol with 2 g (6.9 mmol) of methyl 4-iodo-2-methoxybenzoate, 2.1 g (75%) of the expected ester were obtained, after chromatography on a silica column eluted with dichloromethane, in the form of a yellow oil.
