- Nucleophilic Amination and Etherification of Aryl Alkyl Thioethers
-
A transition-metal-free protocol capable of synthesizing diarylated aniline derivatives is reported. This method could be further employed to prepare aryl alkyl ethers. A wide range of thioethers, anilines, as well as alcohols were tolerated thanks to the mild reaction conditions. The strength of our method was demonstrated by performing a gram-scale reaction (20 mmol) followed by conversion of the nitrile group into synthetically useful aldehyde, ketone, and carboxylic acid.

- Metal-Free Etherification of Aryl Methyl Ether Derivatives by C-OMe Bond Cleavage
-
A general and efficient protocol was developed for the synthesis of aryl alkyl ethers through metal-free C-OMe bond cleavage under mild reaction conditions. This process displays a wide scope of methoxyarenes and alcohols, including primary, secondary, and tertiary alcohols, as well as natural products, pharmaceuticals, and biologically active alcohols. DFT calculations and experimental results simultaneously confirm that a potassium ion plays a critical role in the activation of methoxy group via binding with the nitrile and provide support for an SNAr mechanism.

- (7-Benzyloxy-2,3-dihydro- 1H -pyrrolo[1,2-a]indol-1-yl)acetic acids as S1P1 functional antagonists
-
S1P1 is a validated target for treatment of autoimmune disease, and functional antagonists with superior safety and pharmacokinetic properties are being sought as second generation therapeutics. We describe the discovery and optimization of (7-benzyloxy-2,3-dihydro-1H-pyrrolo[1,2-a]indol-1-yl)acetic acids as potent, centrally available, direct acting S1P1 functional antagonists, with favorable pharmacokinetic and safety properties.
