Descrição geral

Cyclopentanone is a cyclic ketone that occurs in allium species, beef, cheese, and chicken. It is generally used as a fragrance ingredient in fragrances and in non-cosmetic products.

Aplicação


  • High-oxygen-modified atmospheric packaging delays flavor and quality deterioration in fresh-cut broccoli.: This research investigates the impact of high-oxygen-modified atmospheric packaging on the preservation of fresh-cut broccoli. Cyclopentanone is identified as a significant compound in the aroma profile, contributing to the understanding of packaging technologies that maintain food quality and extend shelf life. (He et al., 2024).

  • Selective production of methylindan and tetralin with xylose or hemicellulose.: The study focuses on the selective production of methylindan and tetralin using xylose or hemicellulose, with Cyclopentanone playing a key role in the catalytic processes. This research provides insights into sustainable chemical production from biomass-derived feedstocks. (Zou et al., 2024).

  • Synthesis of Hydroxylamine via Ketone-Mediated Nitrate Electroreduction.: This paper presents a novel method for synthesizing hydroxylamine through ketone-mediated nitrate electroreduction, utilizing Cyclopentanone. The findings demonstrate the versatility of Cyclopentanone in electrochemical synthesis and its potential for green chemistry applications. (Jia et al., 2024).

The density functional theory investigation on the mechanism of NHC-catalyzed cycloannulation reaction of the homoenolate derived from butenal with pentenone is studied. The M06-2X/6-31+G** and B3LYP/6-31+G** levels of theory, including the effect of continuum solvation in dichloromethane and tetrahydrofuran, are

The O-TMS-protected diphenylprolinol-catalyzed cascade double Michael addition reactions of alpha,beta-unsaturated aldehydes with a beta-keto ester bearing a highly electron-deficient olefin unit occur smoothly to afford polysubstituted cyclopentanones. This process allows formation of four contiguous stereocenters in the cyclopentanone ring in

We present a theoretical study of vibrationally resolved circular dichroism spectra, both in the adiabatic and non-adiabatic frameworks, with a full account of Franck-Condon and Herzberg-Teller vibrational contributions for the former. Model calculations have been performed on 2(R)-deuteriocyclopentanone, whose chirality
