Trimethylsilyl triflate is a powerful silylating agent for organic compounds and acts as a catalyst which accelerates a variety of nucleophilic reactions in aprotic media. The reactions proceed via one-center, electrophilic coordination of the silyl group to hetero functional groups and exhibit unique selectivities.
The invention provides the compounds represented by the formula (I)
in which, R stands for a dihydroxy-substituted C

bi- or tri-cyclic aliphatic carbocyclic group. These compounds act as nociceptin receptor antagonist, and are useful, for example, as relievers against tolerance to narcotic analgesic, dependence on narcotic analgesic or addiction; analgesic enhancers; antiobestic or appetite suppressors; treating or prophylactic agents for cognitive impairment and dementia/amnesia; agents for treating developmental cognitive abnormality; remedy for schizophrenia; agents for treating neurodegenerative diseases; anti-depressant or treating agents for affective disorder; treating or prophylactic agents for diabetes insipidus; treating or prophylactic agents for polyuria; and remedy for hypotension and the like.

condensation of enol trimethylsllyl ethers with acetals, orthoformate, or 2-acetoxytetrahydrofuran or -pyrans to give the corresponding β-alkoxy carbonylcompounds. Reaction of enolsilylethers and carboxonium triflate ion-pair intermediates occurs via acyclic transition states and exhibits moderate to high erythro selectivity independent of the geometry (E/Z) of the enolsilylethers.
