(8aRS)-8,8a-Dihydro-furo[3,2-f]indolizine-6,9(4H,7H)-dione.

ABSTRACT: The title compound, C(10)H(9)NO(3), is a chiral mol-ecule with one stereogenic carbon atom, but which crystallizes as a racemate in the centrosymmetric space group P2(1)/n. The central six-membered ring of the indolizine moiety adopts a definite envelope conformation, while the conformation of the oxopyrrolidine ring is close to that of a flat-envelope with a maximum deviation of 0.352?(1)?Å for the flap atom.

Project description:In the title compound, C(18)H(15)NO(3), the fused benzopyran and pyridine rings are essentially coplanar [r.m.s. deviation = 0.0533 Å with a maximum deviation of 0.080 (1) Å for a benzene C atom]. The cyclo-hexa-none ring adopts an envelope conformation with the dimethyl-substituted C atom 0.660 (2) Å out of the plane formed by the remaining ring atoms (r.m.s. deviation = 0.0305 Å). The dihedral angle between the mean planes of the pyran and cyclo-hexa-none rings is 12.95 (6)°. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds, leading to chains running along [011].

2-Chloro-8,8-dimethyl-8,9-dihydro-7H-chromeno[2,3-b]quinoline-10,12-dione.

Project description:The asymmetric unit of the title compound, C(18)H(14)ClNO(3), contains two independent mol-ecules (A and B). In both mol-ecules, the cyclo-hexa-none ring has a chair conformation. The dihedral angles between the pyran ring and the pyridine and chloro-phenyl rings are 2.13 (9) and 2.19 (9)°, respectively, in A, and 0.82 (9) and 1.93 (9)°, respectively, in B. The carbonyl O atoms deviate from the pyran and benzene rings to which they are attached by -0.092 (2) and 0.064 (2) Å, respectively, in A, and by -0.080 (2) and -0.063 (2) Å, respectively, in B. In the crystal, the A mol-ecules are linked via C-H⋯O hydrogen bonds, forming double-stranded chains along [100]. They lie parallel to the double-stranded chains formed by the B mol-ecules, which are also linked via C-H⋯O hydrogen bonds. The chains stack up the c axis in an -A-A-B-B-A-A- manner, with a number of π-π inter-actions involving A and B mol-ecules; the centroid-centroid distances vary from 3.4862 (11) to 3.6848 (11) Å

(8aR,9R)-9-Hy-droxy-7,8,8a,9-tetra-hydro-furo[3,2-f]indolizin-6(4H)-one.

Project description:The title compound, C(10)H(11)NO(3), crystallizes with four independent mol-ecules in the asymmetric unit. Their geometries are very similar and corresponding bond distances are almost identical. The central six-membered ring of the indolizine moiety adopts a envelope conformation [the displacement of the flap atom (the C atom opposite the N atom) being 0.539?(2), 0.548?(3), 0.509?(3) and 0.544?(3)?Å in the four molecules], while the conformation of the oxopyrrolidine ring is close to that of a flat envelope. The displacements of the non-fused C atom opposite the C=O group of the pyrrolidine ring of the four mol-ecules are 0.366?(3), 0.335?(3), 0.173?(3) and -0.310?(3)?Å. In the crystal, O-H?O hydrogen bonds link the mol-ecules into chains, which run parallel to the c axis. The absolute configuration was assigned from the synthesis.

The in-vitro anticancer activities of these compounds were evaluated against four human tumor cell lines. Among all the synthesized derivatives, compound 4i, which has substituent 3-hydroxy-4-methoxyphenyl is found to have the highest GI50 value of 32.7 ?M, 55.3 ?M, 34.3 ?M, 28.9 ?M for MCF-7, K562, HeLa and PC-3 cancer cell lines respectively. A docking study of the newly synthesized compounds were performed, and the results showed good binding mode in the active site of thymidylate synthase enzyme. ADME properties of synthesized compounds were also studied and showed good drug like properties.
