Usage

General Description

4-Methyl-2-nonanone, also known as methyl nonyl ketone, is a chemical compound with the molecular formula C10H20O. It is a ketone that is commonly used as a flavoring agent and fragrance ingredient in various products such as perfumes, cosmetics, and food. It has a fruity, raspberry-like odor that is often described as sweet and floral. 4-Methyl-2-nonanone can also be found in natural sources such as oranges, black currants, and other fruits, as well as in essential oils. In addition to its uses in the fragrance and flavor industry, this chemical is also utilized as a solvent and intermediate in organic synthesis. However, it is important to handle 4-Methyl-2-nonanone with care, as it is flammable and may cause skin and eye irritation upon contact.

Copper-catalysed asymmetric conjugate addition of organometallic reagents to linear enones

Methods for enantioselective 1,4-addition of main-group organometallics to linear enones are overviewed. Thiourethane and thioether 1,1-binaphthyl- based ligands are effective for copper-catalysed 1,4-addition of ZnEt2 and AlR3 (R=Me, Et) to trans-alkyl-3-en-2-ones; enantioselectivities of up to 72% e.e. are attained. In comparison 1,4-addition of ZnEt2 to 2- cyclohexenone proceeds in up to 77% e.e. with the same ligand family. (C) 2000 Elsevier Science Ltd.
