Fructose is widely used in the food industry. However, it may be involved in diseases by generating harmful advanced glycation end-products. We have designed and synthesized a novel fluorescent probe for fructose detection by combining a phenylboronic acid group with a BODIPY-based hydrophobicity probe. This probe showed a linear fluorescence response to D-fructose concentration in the range of 100-1000 μM, with a detection limit of 32 μM, which is advantageous for the simple and sensitive determination of fructose. This study involved multiple reactions and reactants, such as 2-Methoxyethylamine (cas: 109-85-3Related Products of 109-85-3).

2-Methoxyethylamine (cas: 109-85-3) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Related Products of 109-85-3

Nickel-Catalyzed Suzuki-Miyaura Cross-Coupling Involving C-O Bond Activation was written by Morishige, Aoi;Iyori, Yasuaki;Chatani, Naoto. And the article was included in Helvetica Chimica Acta in 2021.Formula: C12H17BO3 The following contents are mentioned in the article:

An efficient Suzuki-Miyaura cross-coupling reaction of ortho-phenoxy-substituted aromatic amides with aryl boronates is described [e.g., I + II → III (85%) in presence of Ni(cod)₂, 3,4,7,8-Me₄Phen, LiOBu-t and CsF in DMF]. The use of LiO^tBu is crucial for the success of the reaction. An amidate anion, which is formed through deprotonation of the amide NH bond by LiO^tBu, functions as a directing group to activate a C-O bond. This study involved multiple reactions and reactants, such as 2-(3-Methoxyphenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 1003858-50-1Formula: C12H17BO3).

2-(3-Methoxyphenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 1003858-50-1) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides. Formula: C12H17BO3

Hypervalent Iodine(III) in Direct Oxidative Amination of Arenes with Heteroaromatic Amines was written by Manna, Srimanta;Serebrennikova, Polina O.;Utepova, Irina A.;Antonchick, Andrey P.;Chupakhin, Oleg N.. And the article was included in Organic Letters in 2015.Reference of 562085-85-2 The following contents are mentioned in the article:

A novel, mild, and practical method of amination of simple nonfunctionalized arenes under metal free conditions has been developed. The approach allows coupling of electron-rich arenes with amino derivatives of electron-deficient heterocycles providing rapid access to scaffolds of bioactive compounds and is based on the application of the hypervalent iodine(III) reagent as an oxidant. Regioselective functionalization of C-H bonds of arenes by the formation of C-N bonds under organocatalytic conditions was demonstrated. This study involved multiple reactions and reactants, such as N-(4-Methoxyphenyl)pyridin-3-amine (cas: 562085-85-2Reference of 562085-85-2).

N-(4-Methoxyphenyl)pyridin-3-amine (cas: 562085-85-2) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Reference of 562085-85-2

A new reagent, 2-azidoethane-1-sulfonylfluoride (ASF) was synthesized from 2-chloroethane-1-sulfonyl fluoride in 50g-scale with 87% yield. This novel reagent possesses two selectively clickable functionalities to be used for both CuAAC and SuFEx click reactions. The application of this reagent ASF to the construction of a class of novel 1,2,3-triazole derived S(VI)-F analogs was achieved in a quick, efficient and atom-economical manner. Orthogonally clickable construction of a new class of dendrimers was also accomplished. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Category: ethers-buliding-blocks).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Category: ethers-buliding-blocks

We introduce the efficient Fmoc-SPPS and peptoid synthesis of Q-proline-based, metal-binding macrocycles (QPMs), which bind metal cations and display nine functional groups. Metal-free QPMs are disordered, evidenced by NMR and a crystal structure of QPM-3 obtained through racemic crystallization Upon addition of metal cations, QPMs adopt ordered structures. Notably, the addition of a second functional group at the hydantoin amide position (R₂) converts the proline ring from Cγ-endo to Cγ-exo, due to steric interactions.
