A compound is shown in formula (I). The derivatives of the compound include a stereoisomer, a pharmaceutically acceptable salt, a solvate, a prodrug, a metabolite, a deuterated derivative. The compound is a structurally novel substituted imidazole formate derivative. Substituted imidazole formate derivatives are used in preparing a drug with sedative, hypnotic and/or anesthetic effects, as well as a drug that can control the state of epilepsy. The compound has a good inhibitory effect on the central nervous system, and provides a new option for clinical screening of and/or preparation of a drug with sedative, hypnotic and/or anesthetic effects and controlling the state of epilepsy.

A conceptually novel approach is described for the synthesis of six‐membered cyclic carbonates derived from carbon dioxide. The approach utilizes homoallylic precursors that are converted into five‐membered cyclic carbonates having a β‐positioned alcohol group in one of the ring substituents. The activation of the pendent alcohol group through an N‐heterocyclic base allows equilibration towards a thermodynamically

1-(2,3-Epoxypropyl)-1-cyclohexanol (1) and its methyl analogues (2 and 3), when treated with base in 75% aqueous dimethyl sulfoxide, gave the corresponding oxetanes (9–11) as the main products, while treatment of compound 1 under anhydrous conditions afforded the oxolane dimer (17) as the sole identified product.
