Reaktionsschritte
Into a solution containing 2,2-bisethoxycarbonyl-5-norbornene (10 g) in dry tetrahydrofuran (100 ml) was added a mixture of lithium aluminum hydride (4.3 g) and dry tetrahydrofuran (100 ml) with stirring at room temperature. The reaction mixture was refluxed for 2 hours. After consumption of excess LiAlH4 by addition of water, the reaction mixture was concentrated to give a residue, which was extracted with chloroform. The extract was washed with a saturated NaCl solution, dried and concentrated to give as a solid substance 2,2-bishydroxymethyl-5-norbornene (Compound No. 21-1) (9.1 g), M.P., 108°-110° C. (recrystallization from isopropanol). IRνmaxNujol (cm-1): 3300, 2950, 1020.
