The present disclosure relates to bifunctional compounds, which find utility as modulators of tau protein. In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a VHL or cereblon ligand which binds to the E3 ubiquitin ligase and on the other end a moiety which binds tau protein, such that tau protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of tau. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of tau protein. Diseases or disorders that result from aggregation or accumulation of tau protein are treated or prevented with compounds and compositions of the present disclosure.

The present invention relates to bifunctional compounds, which find utility as modulators of targeted ubiquitination, especially inhibitors of a variety of polypeptides and other proteins which are degraded and/or otherwise inhibited by bifunctional compounds according to the present invention. In particular, the present invention is directed to compounds, which contain on one end a VHL ligand which binds to the ubiquitin ligase and on the other end a moiety which binds a target protein such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of that protein. The present invention exhibits a broad range of pharmacological activities associated with compounds according to the present invention, consistent with the degradation/inhibition of targeted polypeptides.

base-induced dearomative [2,3] sigmatropic rearrangement of amino acid ester-derived ammonium salts followed by 1,4-elimination produced α-(ortho-vinylphenyl)amino acid esters. The reaction of azetidine-2-carboxylic acid-derived ammonium salt, (1S,2S,1′R)-3b, proceeded with a perfect N-to-C chirality transfer to afford α-(ortho-vinylphenyl)azetidine-2-carboxylic acid ester, (R)-5 (99% ee). On the other hand

(R)-p-bromostyrene oxide. The exocyclic positions opened the epoxide at the alpha-carbon. Epoxide ringopening by the nitrogen at the 7-position showed little preference for the alpha- or beta-carbons in reactions with p-methylstyrene oxide. However, the p-bromostyrene oxide favored reaction at the beta-carbon almost 4-fold over reaction at the alpha-carbon. Almost total inversion of stereochemistry was found
Highly α-position regioselective ring-opening of epoxides catalyzed by halohydrin dehalogenase from <i>Ilumatobacter coccineus</i>: a biocatalytic approach to 2-azido-2-aryl-1-ols
Halohydrindehalogenases are usually recognized as strict β-position regioselective enzymes in the nucleophile-mediated ring-opening of epoxides. Here we found the HheG from Ilumatobacter coccineus exhibited excellent α-position regioselectivity in the azide-mediated ring-opening of styrene oxide derivatives 1a–1k, producing the corresponding 2-azido-2-aryl-1-ols 2a–2k with the yields up to 96%.
