Abstract
Here we report the challenging O-trifluoromethylation of carboxylic acids via the formation and activation of acyloxy(phenyl)trifluoromethyl-λ3-iodanes. The method provides an easy access to various potentially valuable and hitherto elusive trifluoromethyl carboxylic esters. A remarkably wide range of substrates with commonly encountered functional groups are compatible with this reaction, including aromatic and aliphatic carboxylic acids, as well as Food and Drug Administration (FDA) approved drugs and pharmaceutically relevant molecules. The reaction mechanism and the origins of the enhanced reactivity by zinc chloride (ZnCl2) were discussed from experimental evidence and density functional theory (DFT) calculation.

Design, synthesis and evaluation of heterocyclic 2-phenylacetate derivatives as water-soluble rapid recovery hypnotics. Bioorg Med Chem Lett 2023; 82:129165. [PMID: 36736494 DOI: 10.1016/j.bmcl.2023.129165] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Revised: 01/26/2023] [Accepted: 01/28/2023] [Indexed: 02/01/2023]
Abstract
In this work, a series of novel heterocyclic 2-phenylacetate derivatives were designed and synthesized as water-soluble and rapid recovery hypnotic agents. After introducing heterocyclic ring to the amide group of propanidid, the obtained propanidid derivatives showed greatly improved hydrophilicity and good anesthetic activity. In three animal experiments (mice, rats, and rabbits), compounds 13-15 showed potent hypnotic potency (HD50 = 7.6, 6.5, 7.4 mg/kg in rabbits, respectively) and higher therapeutic indexes (TI = 17.3, 16.6, 15.2 in rabbits, respectively) than propanidid (TI = 14.7 in rabbits) or propofol (TI = 5.4 in rabbits). Moreover, the recovery time of compounds 13-15 (time to walk, 96.6, 79.6, 81.4 s in rabbits, respectively) were shorter than that of propanidid (124.5 s in rabbits) or propofol (425.3 s in rabbits). The experimental results suggested the potential of compounds 13-15 as water-soluble anesthetics with rapid recovery profile.

Abstract
In this paper, we designed and synthesized a series of novel phenylpiperazine-phenylacetate derivatives as rapid recovery hypnotic agents. The best compound 10 had relatively high affinity for the GABAA receptor and low affinity for thirteen other off-target receptors. In three animal models (mice, rats, and rabbits), compound 10 exerted potent hypnotic effects (HD50 = 5.2 mg/kg in rabbits), comparable duration of the loss of righting reflex (LORR), and significant shorter recovery time (time to walk) than propanidid. Furthermore, compound 10 (TI = 18.1) showed higher safety profile than propanidid (TI = 14.7) in rabbits. Above results suggested that compound 10 may have predictable and rapid recovery profile in anesthesia.
