“…This conclusion follows from spin decoupling studies on 31-H and 7. 6 Hz, respectively, in agreement with prevailing dihedral angles of ca. 100 and Oo.l5 Interestingly, both of these coupling constants are somewhat larger than those previously reported for benz~norbornenel~ and norbornene.…”

“…The action of methanolic potassium Scheme I cyanide on m-dinitrobenzene (4) gave the previously described 2-nitro- 6-methoxybenzonitrile (5)4 which was reduced directly to 6 with stannous chloride in hydrochloric acid.5 Subsequent saponification of 6 afforded 6-methoxyanthranilic acid (7)6 in 17% overall yield. Exposure of 7 to isoamyl nitrite in the presence of cyclopentadiene resulted in the formation of 8 (57%).…”
