Аннотация:Molecular structures of oxime 6-oxo-indolo[2,3-b]-bicyclo[3.3.1]non-2-en 1 and 6-oxo-(5-methoxy-indolo[2,3-b])-bicyclo[3.3.1]non-2-en 2 were determined by X-ray crystal investigation. It was revealed that oxime 1 has anti-configuration in respect to indole-containing framework, and both compounds adopt half-chair-chair-conformation. The distortion of rings was evaluated by calculation of the ZP- and CP-puckering parameters. The presence of the methoxy-group in compound 2 was found to lead to the changes in molecular packing in comparison with structure 1.
