We envisioned applying our direct amination protocol to α-branched carboxylic acids, which would provide a general and rapid synthetic method for accessing non-racemic α,α-disubstituted α-amino acids that has to date been elusive. Indeed, when we reacted racemic α-branched carboxylic acids ...
Synthesis of higher carboxylic acids using CO2 and H2 is of great importance, because CO2 is an attractive renewable C1 resource and H2 is a cheap and clean reductant. Herein we report a route to produce higher carboxylic acids via reaction of ethers wit
Besides, its product categories are including Pharmaceutical Intermediates; Aromatic Carboxylic Acids, Amides, Anilides, Anhydrides & Salts; Cyclopropanes; Simple 3-Membered Ring Compounds. The characteristics of this chemical are as follows: (1)ACD/LogP: 0.08; (2)# of Rule of 5 Violations: 0; ...
A broad substrate scope ranging from aromatic to aliphatic carboxylic acids was tested and TtCAR showed activity for all substrates. High specific activities for aromatic substrates and short chain aliphatic substrates were observed, comparable to those of NcCAR, the first type III fungal CAR. Tt...
LAT1-IN-1 (BCH) is a selective and competitive inhibitor of large neutral amino acid transporter 1 (LAT1) significantly inhibit cellular uptake of amino acids and mTOR phosphorylation, which induces the suppression of cancer growth and apoptosis[1][2][3]. 2-Amino-2-norbornanecarboxylic acid...
carboxylic acids. Several control experiments were conducted to interrogate the intermediates involved in this reaction (Fig.2a). Under the standard conditions, methyl phenylacetate failed to afford any α-amination product, which was in a stark contrast with the productive PAA substrate, supporting ...
Omega-3 free fatty acids (or omega-3 carboxylic acids [OM3-CA; Epanova]) contain 50% to 60% eicosapentaenoic acid (EPA) and 15% to 25% docosahexaenoic acid (DHA) along with other potentially active omega-3 fatty acids in free fatty acid form. They are a more bioavailable form of omega...

carboxylic acids and alkenyl triflates with the synergistic catalysis of cyclo-octa-1,5-diene(tetramethyl-1,4-benzoquinone)nickel and visible light under an air atmosphere, thus avoiding the need for a glovebox or a Schlenk line. A wide range of aromatic carboxylic acids and cyclic and acyclic...
