Usage

General Description

Ethyl 2-methyl-2-butenoate, also known as ethyl tiglate, is a chemical compound with the molecular formula C7H12O2. It is a clear, colorless liquid with a fruity and sweet odor, commonly used as a flavoring agent in the food and beverage industry. Ethyl tiglate is naturally found in fruits such as strawberry, apple, and grapes, and is also used in perfumes and cosmetics for its pleasant aroma. It is synthesized through the esterification of ethyl alcohol with tiglic acid, and it is considered safe for consumption in small amounts. In addition to its use in flavors and fragrances, ethyl tiglate is also utilized in organic synthesis as a precursor to various compounds.

Catalytic Asymmetric Vinylogous Mukaiyama-Aldol (CAVM) reactions: The enolate activation

The Catalytic Asymmetric Vinylogous Mukaiyama (CAVM) reactions of various aldehydes with dienolate 1 using different enolate activations (CuF·(S)-TolBinap, t-BuOCu·(S)-Tol-Binap, and various chiral nonracemic ammonium fluorides derived from cinchona alkal

Highly Enantioselective Iridium-Catalyzed Hydrogenation of Conjugated Trisubstituted Enones

Asymmetric hydrogenation of conjugated enones is one of the most efficient and straightforward methods to prepare optically active ketones. In this study, chiral bidentate Ir-N,P complexes were utilized to access these scaffolds for ketones bearing the stereogenic center at both the α- and β-positions. Excellent enantiomeric excesses, of up to 99%, were obtained, accompanied with good to high isolated yields. Challenging dialkyl substituted substrates, which are difficult to hydrogenate with satisfactory chiral induction, were hydrogenated in a highly enantioselective fashion.

2-alkyl substituted crotonic acid and ester synthesis method thereof

The invention provides a 2-alkyl substituted crotonic acid and an ester synthesis method thereof.The ester synthesis methodincludes the following steps that 2-alkyl butyric acid, a first catalyst and halogen are used as raw materials to synthesize 2-halogeneated-alkyln-butyric acid; the 2-halogeneated-alkyln-butyric acid, a solvent and inorganic base are used as raw materials to synthesize 2-alkyl crotonic acid; the 2-alkyl crotonic acid, a second catalyst and alcohol are used as raw materials to synthesize 2-alkyl crotonic acid ester. The 2-alkyl substituted crotonic acid and the ester synthesis method have the advantages that the solvents used in all reaction steps are recyclable, a water phase is recycled after finished product filtering, no wastewater is discharged, and a byproduct haloid acid (particularly referring to hydrobromic acid and hydrochloric acid) is obtained after halogen hydridetail gas is absorbed.
