<3+4> and <3+5> Annulation Reactions of alpha-(Phenylthio) Dicarbonyl Electrophiles with Bis(trimethylsilyl) Enol Ethers: Synthesis of Highly Functionalized Medium Ring Cycles

The <3+4> and <3+5> annulations of bis(trimethylsilyl) enol ethers with 1,4- and 1,5-dicarbonyl electrophiles bearing alpha-phenylthio substituents leads to the formation of bicyclic <3.2.1> and <3.3.1> ethers with good regiochemical and stereochemical control.Subsequent oxidation of the phenylthio moiety followed by reduction with SmI2 constitutes a high-yielding and regioselective process for cleavage of the bridging ether linkage.The overal strategy provides a synthetic pathway for the synthesis of highly functionalized medium ring carbocycles.

Effect of end-point temperature and degree of doneness on sensory and instrumental flavor profile of beefsteaks

Beef M. longissimus thoracis et lumborum was used to investigate the effects of 6 end-point temperatures on flavor and texture. Steaks cooked to medium temperature were associated with 4-heptanolide, whereas those cooked to higher temperatures were associated with pyrazines and hexanol. These steaks were also associated with flavor attributes, such as roasted, burnt, and beefy. However, consumers did not find differences in flavor liking of steaks (P > 0.05) cooked to 6 end-point temperatures. Although steaks cooked to lower temperatures were liked for their tenderness and juiciness, overall liking scores were not affected by end-point temperature. Thus both flavor and tenderness play an important role in consumer satisfaction.

Pesticides in honey: A review on chromatographic analytical methods

Honey is a product of high consumption due to its nutritional and antimicrobial properties. However, residues of pesticides, used in plagues’ treatment in the hive or in crop fields in the neighborhoods, can compromise its quality. Therefore, determination of these contaminants in honey is essential, since the use of pesticides has increased significantly in recent decades because of the growing demand for food production. Furthermore, pesticides in honey can be an indicator of environmental contamination. As the concentration of these compounds in honey is usually at trace levels and several pesticides can be found simultaneously, the use of highly sensitive and selective techniques is required. In this context, miniaturized sample preparation approaches and liquid or gas chromatography coupled to mass spectrometry became the most important analytical techniques. In this review we present and discuss recent studies dealing with pesticide determination in honey, focusing on sample preparation and separation/detection methods as well as application of the developed methods worldwide. Furthermore, trends and future perspectives are presented. & 2015 Elsevier B.V. All rights reserved.

Solid acid catalysis of tandem isomerization-lactonization of olefinic acids

The conversion of unsaturated acids to gamma-lactones is catalyzed by the solid sulfonic acid catalysts Amberlyst-15 and Nafion SAC-13 in refluxing chlorobenzene. For 3- and 4-enoic acids, in which double bond migration is not required for gamma-lactone formation, yields are 95-100%. For 5-, 6-, 9-, and 10-enoic acids, the lactone yield decreases from 95% to 25% as the distance between the olefin and carboxylic acid groups increases. Amberlyst-15 is the preferred catalyst in these reactions because of its lower cost and reusability.
