Usage

Description

Isoamyl benzoate is an organic compound with a fruity, slightly pungent odor, commonly used as a fragrance ingredient in perfumery and cosmetics.
Used in Perfumery and Cosmetics Industry:
Isoamyl benzoate is used as a fragrance ingredient for its pleasant and fruity scent, enhancing the overall aroma of various perfumes and cosmetic products.

Preparation

By transesterification of methyl benzoate and isoamyl alcohol in the presence of potassium isoamylate; also by heating benzyl chloride and isoamyl acetate.

Metabolism

Benzoic acid is metabolized in the mammalian body after conjugation with glycine to form hippuric acid and benzoylglucuronic acid, which are excreted in the urine(Williams, 1959).

LiHMDS: Facile, highly efficient and metal-free transesterification under solvent-free condition

Transesterification is one of the important organic reactions employed in numerous industrial as well as laboratory applications for the synthesis of various esters. Herein, we report a rapid, highly efficient, and transition metal-free transesterification reaction in the presence of LiHMDS under solvent-free conditions. The transesterification reaction was carried out with three different benzoate esters and a wide range of primary and secondary alcohols (from C3-C18) in good to excellent yields (45 examples). By considering the commercial role of esters, this method will be promising for the facile synthesis of esters in industry-relevant applications.

Zn-Mediated Hydrodeoxygenation of Tertiary Alkyl Oxalates

Herein we describe a general, mild, and scalable method for hydrodeoxygenation of readily accessible tertiary alkyl oxalates by Zn/silane under Ni-catalyzed conditions. The reduction method is suitable for an array of structural motifs derived from tertiary alcohols that bear diverse functional groups, including the synthesis of a key intermediate en route to estrone.

Metal catalyst-free photo-induced alkyl C-O bond borylation

Metal catalyst free, blue visible light-induced C-O bond borylation of unactivated tertiary alkyl methyl oxalates has been developed to furnish tertiary alkyl boronates. From the secondary alcohols activated with imidazolylthionyl, moderate yields of boronates were attained under standard photo-induced conditions. Preliminary mechanistic studies confirmed the involvement of a (DMF)2-B2cat2 adduct that weakly absorbs light at 437 nm so as to initiate a Bcat radical. A radical-chain process is proposed wherein the alkyl radical is engaged. This journal is
