, p. 971 - 977 (2007/10/03)
The acid and base catalyzed isomerization of some tricyclic 2-pyrazolines with N-Carbamoyl-, N-thiocarbamoyl- and N-phenyl substituents was investigated. Starting from cis or trans 3-H, 3a-H diastereomers, equilibrium mixtures of cis and trans diastereomers were prepared which were separated and subsequently studied by 1H NMR and 13C NMR spectroscopy. A mechanism for the isomerization of the pyrazolines is suggested, supported by a deuterium exchange at C-3a.

, p. 489 - 493 (2007/10/02)
Hexahydrobenzocycloheptapyrazoles have been synthesized by treating 2-benzylidene-1-benzosuberone with hydrazine derivatives.The cis and trans isomers have been distinguished and conformational equilibria studied by NMR techniques.

, p. 481 - 486 (2007/10/02)
A series of bi- and tricyclic 4,5-dihydropyrazoles have been studied by 1H n.m.r. and 13C n.m.r. spectroscopy and X-ray crystallography.They were synthesised by treating the corresponding mono- and dibenzylidenecycloalkanones and 2-benzylidene-3,4-dihydro
