Synthesis of 2-Oxa and 2-Aza Analogs of Pyrrolizidine-3,5-diones (Lukes-Sorm Dilactam)
摘要:
The synthesis of 2-oxa and 2-aza analogs of pyrrolizidine-3,5-dione (Lukes-Sorm dilactam), which has amnesia reversal activity, is reported. Optically active (+)-2-oxa and (+)-2-aza analogs [(+)-2 and (+)-3] and racemic 2-aza analog and its 1-methoxycarbonyl derivatives [(+)-3 and (+)-13 and -14] were prepared from (-)-S-pyroglutamic acid and succinimide, respectively.

Described herein are new, selective modulators of the 5 -HT7 receptor. These selective compounds can be useful for the treatment of CNS and non-CNS indications. Compounds described herein can be selective in targeting 5-HT7 receptors as compared to other receptors and/or by selective targeting 5-HT7 receptors expressed in certain tissues or organs, thereby effective selectivity through a particular partitioning profile of the 5- HT7 modulator.

chemistry made possible the prediction of the three-dimensional structures of γ-lactamanalogues of penems and carbapenems before the analogues were made. Molecular superpositioning showed that these novel structures with a 7β-acylamino side-chain present the pharmacophoric groups in close spatial similarity to the groups in biologically active cephalosporin and penicillin antibiotics. This suggests
