In Memoriam: Robert Emmons Kissling (1923–2013)
R Kissling, a pillar of US Center for Disease Control (CDC) infectious diseases programs through an era of great programmatic and institutional growth (1947– 1973), died November 13, 2013 at his home in North Carolina. Through his years at CDC, Bob led investigations of great diversity and impact, always with the same sense of openness, integrity, composure, and respect for everyone involved. T...
متن کاملPsychological Science Priyanka D . Joshi and Nathanael J . Fast Power and Reduced Temporal
Decision makers generally feel disconnected from their future selves, an experience that leads them to prefer smaller immediate gains to larger future gains. This pervasive tendency is known as temporal discounting, and researchers across disciplines are interested in understanding how to overcome it. Following recent advances in the power literature, we suggest that the experience of power enh...
متن کاملA convenient and stereoselective synthesis of 11Z-3,4-didehydroretinal by Horner-Emmons reaction using diphenyl phosphonate.
A convenient synthesis of 3,4-didehydroretinal was developed. The Horner-Emmons reaction between 3,4-didehydro-beta-ionone and diphenyl phosphonate in the presence of crown ether gave the retinonitrile as an isomeric mixture, in which the newly produced double bond was predominantly 11Z-form. After separation of the 11Z-form retinonitrile, it was converted into the corresponding retinal in good...
متن کاملRoute to α-Aryl Phosphonoacetates: Useful Synthetic Precursors in the Horner–Wadsworth–Emmons Olefination
A versatile and general catalytic strategy has been developed for the α-arylation of phosphonoacetates utilizing parallel microscale experimentation. These α-substituted phosphonoacetates are widely useful, notably as substrates in the Horner-Wadsworth-Emmons-type olefinations. However, the current routes to these products involve harsh conditions, limiting the variety of functionality. The rep...
متن کاملSynthesis of functionalised 4H-quinolizin-4-ones via tandem Horner-Wadsworth-Emmons olefination/cyclisation.
4H-Quinolizin-4-ones are a unique class of heterocycle with valuable physicochemical properties and which are emerging as key pharmacophores for a range of biological targets. A tandem Horner-Wadsworth-Emmons olefination/cyclisation method has been developed to allow facile access to substituted 4H-quinolizin-4-ones encoded with a range of functional groups.
