  • Publication number: 20230265093
    Abstract: Disclosed are novel small molecules, methods of synthesis of the small molecules, and uses of the small molecules for modulating activity of the human serotonin receptor 2C (5-HT2c), preferably selectively. The small molecules have a substituted beta-carboline core structure, which optionally may be saturated at one or more bonds to provide a dihydro-beta-carboline core or a tetrahydro-beta-carboline core. The small molecules may be administered to treat and/or prevent diseases, disorders, and/or conditions associated with human serotonin receptor 2C (5-HT2c) including psychiatric, mental, and/or neurological diseases, disorders, and conditions such as cognitive impairment, addiction, and obsessive compulsive disorder. The disclosed small molecules also may be administered to treat and/or prevent obesity, for example, via appetite suppression.

  • Patent number: 11691958
    Abstract: Disclosed are enantioselective cross dehydrogenative coupling reactions for synthesizing tetrahydropyran compounds. Novel tetrahydropyran compounds may be synthesized by the disclosed methods as well as tetrahydropyran precursor compounds for synthesizing various naturally occurring compounds. The enantioselective cross dehydrogenative coupling reactions utilize in situ Lewis Acid activation in combination with oxidative formation of an oxocarbenium ion to provide a highly efficient and selective coupling reaction for synthesizing tetrahydropyran compounds.
