Enantioenriched acyclic α‐substituted β‐hydroxy amides are valuable compounds in chemical, material and medicinal sciences, but their enantioselective synthesis remains challenging. A catalytic kinetic resolution (KR) of such amides with selectivity factor(s) up to >200 is developed via enantioselective acylation of primary alcohol with N‐heterocyclic carbene. An enhanced selectivity for the catalytic
scale-up to afford the products in multigram quantities [in the case of (-)-4, >100-g quantities). These convenient approaches facilitate structure-activity relationship studies including in vivo cardiovascular adverse effects.

A method of treatment of: i) HIV-1 infections in mammals, including humans; or ii) HBV infections in mammals, including humans; which method comprises the administration to the human in need of such treatment, an effective amount of the (R)-enantiomer of the triphosphate of a compound of formula (A) or a pharmaceutically acceptable salt thereof; and compounds for use in the method.
Provided are cycloalkanopyridine derivatives of formula [I]:
[wherein the symbols are the same as those stated in the description]. The compounds act as a nociceptin receptor antagonist, and are useful as medicines for diseases associated with a nociceptin receptor, for example, as a reliever against tolerance to a narcotic analgesic; a reliever against dependence on or addiction to a narcotic analgesic; an analgesic enhancer; an antiobesitic or appetite suppressor; a treating or prophylactic agent for cognitive impairment and dementia/amnesia; an agent for treating developmental cognitive abnormality; a remedy for schizophrenia; an agent for treating neurodegenerative diseases; an anti-depressant or treating agent for affective disorder; a treating or prophylactic agent for diabetes insipidus; a treating or prophylactic agent for polyuria; or a remedy for hypotension.
