Synthesis of Terminal Perfluoroalkyl Enol Ethers and Epoxy Ethers
摘要:
A practical method for the multigram-scale preparation in good yields of terminal perfluoroalkyl enol ethers, using Wittig olefination of perfluoroalkyl ethers, is reported. The corresponding epoxy ethers are available via their m-CPBA epoxidation in good yields.

Several alkyl trifluoromethanesulfonates (triflates) 2 are prepared by reacting alkyl trimethylsilyl ethers 1 with trifluoromethanesulfonic anhydride. The triflates 2 can be used for further reactions without isolation, as illustrated in the preparation of the ether 3 and cumene (4).

order to elucidate the effect of a phenyl group at a remote position on the reactivity and the course of the reaction. The reactivities varied remarkably with the length of the alkyl chain(n); 2>>3 5>6. The rate enhancement was attributed to anchimeric assistance by a remote phenyl group, and the rate depression to the electron-withdrawing inductive effect of a phenyl group.

The discovery and characterization of a novel chemical series of phosphorothioyl-containing imidazopyridines as potent neuropeptide S receptor antagonists is presented. The synthesis of analogues and their structure-activity relationship with respect to the Gq, Gs, and ERK pathways is detailed. The pharmacokinetics and in vivo efficacy of a potent analogue in a food intake rodent model are also included, underscoring its potential therapeutic value for the treatment of sleep, anxiety, and addiction disorders.
