Chiral anion-mediated asymmetric ion pairing chemistry.

Chemical Communications — Fri, 20 Nov 2009 00:34:10 +0100

Authors: Lacour J, Moraleda D Chemical reactions and processes often involve cationic reagents, intermediates or products in prochiral or chiral racemic form. To afford instead non-racemic compounds, an asymmetric ion pairing of the cations with chiral anionic counterions can be considered. This review presents recent examples of the synthesis and use of chiral anions for such stereoselective purposes. PMID: 19920995 [PubMed - as supplied by publisher] (Source: Chemical Communications)

Cinchona-based phase-transfer catalysts for asymmetric synthesis.

Chemical Communications — Fri, 20 Nov 2009 00:34:06 +0100

Authors: Jew SS, Park HG Phase-transfer catalysis is one of the most useful methodologies for practical syntheses given its operational simplicity and mild reaction conditions that enable its application in industrial processes. Cinchona alkaloids have been a popular, natural source of practical organocatalysts due largely to their excellent commercial availability and low cost. Since the first Cinchona alkaloid-derived phase-transfer catalysts was disclosed in 1981, diverse generations of Cinchona-derived phase-transfer catalysts have been developed and successfully applied to various asymmetric syntheses. In this feature article, we describe the generation of Cinchona-derived chiral phase-transfer catalysts according to the development stages and our efforts toward the design of poly...

On This Day in Science History - November 20 - Karl von Frisch and Bees

About.com Chemistry — Fri, 20 Nov 2009 00:05:54 +0100

November 20th is Karl von Frisch's birthday. Frisch was an Austrian biologist who investigated the behavior and senses of bees. He found bees can see in the ultraviolet spectrum of light and are sensitive to polarized light. He also determined the meaning of the 'wiggle dance' that bees perform to inform other bees the distance and direction to sources of pollen and nectar. His investigations into bee life would earn him part of the 1973 Nobel Prize in Medicine. This Prize was the first to deal with the interactive study of humans and animals and help gain recognition of social behavior as a biological science.

Why Is Your Turkey Dry?

About.com Chemistry — Fri, 20 Nov 2009 00:00:00 +0100

While watching the History Channel, I learned why I haven't made a dry turkey. The secret of my success? Impatience. My family circles the roasting turkey, ready to pounce the instant it hits the minimum cooking temperature, which in my house is 170°F. Depending on what you read, the safe/optimum cooking temperature is 160°F to 180°F. The minimum temperature is supposed to protect you from bacteria (mainly Salmonella) and parasites (eww). If you shoot for the lower temperature then the dark meat of the turkey (the legs and thigh) will be tough and underdone. If you aim at the upper end of the temperature range then the dark meat may be fine, but the white meat will be tough and dry. According to the History Channel, at 170° the proteins that comprise turkey meat start t...
