概要

• 論文の詳細を見る

• The crystal structures of 5-hydroxy-3,4-dihydro-2-quinolone (2) and 5-hydroxy-1-methyl-3,4-dihydro-2-quinolone (3) were determined by X-ray analysis. The C (3)-C (4) bond distance of 2,1.430 (9) A, is slightly shorter than a single bond distance. On the other hand, those of the two independent molecules of 3 found in an asymmetric unit, 1.474 (6) A and 1.516 (6) A, are normal with usual thermal parameters for the C (3) atom, probably because of the restriction of the ring puckering by compact crystal packing.
