Novel, Achiral 1,3,4-Benzotriazepine Analogues of 1,4-Benzodiazepine-Based CCK2 Antagonists That Display High Selectivity over CCK1 Receptors
摘要:
A series of 1,3,4-benzotritzepine-based CCK2 antagonists have been devised by consideration of the structural features that govern CCK receptor affinity and the receptor subtype selectivity of 1,4-benzodiazepine-based CCK2 antagonists. In contrast to the latter compounds, these novel 1.3.4-benzotriazepines are achiral, yet they display similar affinity for CCK2 receptors to the earlier molecules and are highly selective over CCK1 receptors.

Chemoselective Synthesis of Asymmetrical Carbonate from Alcohol and Dimethyl Carbonate Catalyzed by Ytterbium(III) Triflate
Abstract Catalyzed by ytterbium(III) triflate, asymmetrical carbonate can be chemoselectively synthesized from alcohols and dimethyl carbonate (DMC) in moderate to good yield under the mild conditions.
