## Abstract The acid catalyzed condensation of 4,5‐diaminopyrazoles and chalcones gave the hitherto unknown 1‐benzyl‐2,4,6‐triphenyl‐2,3‐dihydropyrazolo[3,4‐__b__][1,4]diazepines derivatives. The structure of all products was supported by ir, ^1^H and ^13^C‐nmr and mass spectra.

The structure of the title compound, C~7~H~8~O~3~, was determined in the course of our studies of the synthesis of cyclopenta[1,2-__b__]furan-4-one derivatives. The molecule has four chiral C atoms. The X-ray crystal structure analysis shows the compound to possess an epoxide group with an __endo__

The title compound, C~11~H~16~N~2~ ^2+^·2Cl^−^·H~2~O, is a novel conformationally constrained tricyclic analogue of nicotine, in which the pyridine and pyrrolidine rings of the latter are bridged by a CH~2~ group. As result of this bridge, these two rings are no longer approximately perpendicular as

At 150 K, the tricyclic core of the title compound, C 34 H 31 NO 3 , is close to planar. One of the three 4-methoxyphenyl substituents is twisted out of the plane of the tricyclic core due to steric congestion.
