Milk and dairy products continue to raise concerns with regard to contamination with mycotoxins, most of which have a likely or confirmed carcinogenic status. Such concerns are more serious for certain cheeses due to their frequent contamination with high concentrations of mycotoxins from various sources, including the milk used as a raw material and moulds found as contaminants or purposely added for ripening. Different control measures have been suggested to prevent the formation or to remove mycotoxins in dairy products once formed therein. However, these methods either provide an insufficient degree of protection or are onerous to implement. This review surveys the main mycotoxins associated with dairy products and discusses their health significance. Attention is drawn to the lack of knowledge on the emerging and masked mycotoxins with relevance to dairy products. Known control measures are discussed from the perspective of their application while presenting their strengths and weaknesses.

An unexpected and green synthesis of azapodophyllotoxin derivatives was realized via microwave-assisted multicomponent reactions of dimedone, tetronic acid, and aromatic aldehydes in ammonia water. This protocol has the advantages of environmental friendliness, short reaction time, good yields, low cost, and easy operation.

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research. Reference of 4971-56-6

Growth promoting: The first synthesis of the natural product xanthofulvin (SM-216289) has resolved issues regarding its structural assignment and that described for the natural product 411J. The structurally and biologically related natural product vinaxanthone was similarly prepared through a novel dimerization reaction. Treatment of C. elegans with synthetic xanthofulvin and vinaxanthone enhanced axonal branching.

Dimedone (5,5-dimethylcyclohexane-1,3-dione) is an alicyclic diketone, occasionally considered as building blocks in design and synthesis of a wide variety of heterocycles. The synthetic efficacy of dimedone as a synthon has been presented as a chapter in Advances in Heterocyclic Chemistry in 2009. Due to importance of dimedone and huge numbers of cited references concerning its applications after 2009 till date, in this review we try to update its unique role as a privileged synthon in the synthesis of different heterocyclic compounds.

(Matrix Presented) A novel and highly stereoselective synthesis of aza-spirocycles is described. An application of this methodology is illustrated as a short and concise total synthesis of 2-epi-(±)-perhydrohistrionicotoxin with high diastereomeric control at the aza-spirocenter. An unprecedented decarboxylation of the 2-pyrone ring is observed in this total synthesis effort.

In a hurry to leave! Nosylates act as an excellent leaving group in various palladium-catalyzed cross-couplings, such as Suzuki, Stille, Heck, and Sonogashira reactions (see scheme). Crystalline, stable, and cheap vinyl and aryl nosylates proved better than classical halides and triflates, consistently giving higher yields of coupling products. Their usefulness in C-C bond formation was also demonstrated by the rapid synthesis of the alkaloid dubamine. Copyright
