• 論文の詳細を見る

• Single crystal X-ray analyses of thieno[3,2-a]- and thieno[2,3-b]indolizine derivatives were carried out and their structures were definitively established. The tricyclic ring systems in both molecules were nearly planar and their deviations from the least-squares planes were less than 6.26°. The structural factors for their indolizine moieties were very similar to those for known aromatic indolizines, but those for the thiophene rings were somewhat different. The deviation from co-planarity and the deformation of the thiophene ring in thieno[3,2-a]indolizine were greater than those in thieno[2,3-b]indolizine.
