3,6-二(苯基亚甲基)哌嗪-2,5-二酮 | (Z)-3-(Z)-6-dibenzylidene-2,5-piperazinedione | 74720-33-5 | C18H14N2O2 | 290.321 |
The trans- and (�) cis-isomers of 1,4-dimethyl-and 1,4-diacetyl-3,6-dibenzylpiperazine-2,5-dione were synthesized. The hydriodic acid reduction of 3,6-dibenzylidene-1,4-dimethylpiperazine-2,5-dione gave (�)-cis-3,6-dibenzyl-1,4-dimethylpiperazine-2,5-dione although this product has previously been assigned the trans-geometry. The unknown isolated from the permanganate oxidation of (�)-cis- 1,4-diacetyl-3,6-dibenzylpiperazine-2,5- has been identified as the corresponding trans-isomer.
