Asymmetric Synthesis of Vabicaserin via Oxidative Multicomponent Annulation and Asymmetric Hydrogenation of a 3,4-Substituted Quinolinium Salt
摘要:
An efficient, asymmetric synthesis of the 5-HT2C agonist vabicaserin in four chemical steps and 54% overall yield from commercially available benzodiazepine was achieved. The synthesis was highlighted by a novel oxidative, multicomponent reaction to affect the quinolinium ring assembly in one step followed by an unprecedented asymmetric hydrogenation of a 3,4-substituted quinolinium salt.
