2-Benzoyl-3-cyclohexyl-4-(p-methoxyphenyl)-5-phenylpyrrolidine-3-spiro-3′-chroman-4′-one

“…All the CÐC bond lengths in the aromatic rings (C, D, F and G) and the cyclohexyl ring (B) are comparable with the corresponding literature values of 1.384 (13) and 1.539 (16) A Ê , respectively (Allen et al, 1987). The bond lengths in the pyrrolidine ring (A) are comparable with those reported earlier (Jeyabharathi et al, 2001(Jeyabharathi et al, , 2002Abdul Ajees et al, 2002;Gzella & Wrzeciono, 1990). The bond lengths in the pyran ring (E) in the chromanone moiety are also close to those found in related structures (Jeyabharathi et al, 2002;Abdul Ajees et al, 2001).…”

Indole-3-spiro-N-methyl-2′-pyrrolidine-3′-spiro-9′′-anthracene-2,10′′-dione

“…deviation for all the non-H atoms in the molecules is 0.19 A Ê . The bond lengths in the pyrrolidine moiety are slightly longer than the normal values and are comparable with those already reported (Jeyabharathi et al, 2001;Gzella & Wrzeciono, 1990). This may be due to the spiro-atom character and the steric effect of the bulky groups substituted at C2 and C3.…”

4′-(2-Chlorophenyl)-2,3-dihydro-1′-methyl-3′-nitrospiro[1H-indole-3,2′-pyrrolidin]-2-one

“…The planar nitro group subtends an angle of 75.3 (1) to the mean plane of the pyrrolidine ring. In the planar oxindole moiety, bond lengths C8ÐN7 and N7ÐC6 are similar to values reported in the literature (Jeyabharathi et al, 2001).…”
