Ireland-Claisen rearrangement of 3-acetoxy-11-(tetrahydropyranyloxy)undec-1-ene gives 13-(tetrahydropyranyloxy)-4(E)-tridecen-1-oic acid (I) stereospecifically. Oxidative decarboxylation of I followed by acetylation furnishes (E)-9,11-dodecadien-1-yl acetate in good yield. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Product Details of 50767-78-7).

(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. 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.Product Details of 50767-78-7

A formal total synthesis of taxol aided by an automated synthesizer was written by Doi, Takayuki;Fuse, Shinichiro;Miyamoto, Shigeru;Nakai, Kazuoki;Sasuga, Daisuke;Takahashi, Takashi. And the article was included in Chemistry – An Asian Journal in 2006.Safety of (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate The following contents are mentioned in the article:

A 36-step synthesis was carried out in automated synthesizers to provide a synthetic key intermediate of taxol. A key step involved a microwave-assisted alkylation reaction to construct the ABC ring system from an AC precursor. Subsequent formation of the D ring afforded (±)-baccatin III, a well-known precursor of taxol. This study involved multiple reactions and reactants, such as (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5Safety of (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate).

(2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. 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.

This study involved multiple reactions and reactants, such as Methyl (S)-3-amino-3-(4-fluorophenyl)propanoate hydrochloride (cas: 1246174-74-2Category: esters-buliding-blocks).

Methyl (S)-3-amino-3-(4-fluorophenyl)propanoate hydrochloride (cas: 1246174-74-2) belongs to esters. 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. 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: esters-buliding-blocks

(2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5) belongs to esters. 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. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.HPLC of Formula: 37905-02-5

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. 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.Related Products of 102-09-0
