摘要

The hydrogenation at Raney nickel of the pyrazoline ring in methyl exo-3,4-diazatricyclo [5.2.1.0(2,6)] dec-4-ene-5-carboxylate takes place quantitatively with the preferential formation of the trans isomer of 5-amino-exo-3-azatricyclo[ 5.2.1.0(2,6)] decan-4-one. The 3-methoxycarbonylmethyl-, 3-acetyl-, and 3-nitroso-substituted esters are not hydrogenated under these conditions.
