Asymmetric organocatalysis of the addition of acetone to 2-nitrostyrene using N-diphenylphosphinyl-1,2-diphenylethane-1,2-diamine (PODPEN)
The highly enantioselective addition of acetone to 2-nitrostyrene, using Nâdiphenylphosphinyl-trans-1,2-diphenylethane-1,2-diamine (PODPEN) as catalyst, is described
The diastereoselective Meth-Cohn epoxidation of camphor-derived vinyl sulfones
Some camphor-derived vinyl sulfones bearing oxygen functionality at the allylic position have been synthesized and their nucleophilic epoxidation reactions under Meth-Cohn conditions have been explored. The Îł-oxygenated camphor-derived vinyl sulfones underwent mildly diastereoselective nucleophilic epoxidation reactions, affording the derived sulfonyloxiranes in up to 5.8:1 dr. The observed diastereoselectivities were sensitive to the reaction conditions employed. In contrast, no stereoselectivity was observed in the nucleophilic epoxidation of the corresponding Îł-oxygenated isobornyl vinyl sulfone. A tentative mechanism has been proposed to explain the origins of the diastereoselectivit

Unsound Seeds
With this image of a curtain hiding and at the same time heightening some terrible secret, Max Kalbeck began his review of the first Viennese performance of Richard Straussâs Salome. Theodor W. Adorno picked up the image of the curtain in the context of Straussâs fabled skill at composing non-musical events, when he identified the opening flourish of Straussâs Salome as the swooshing sound of the rising curtain. If this is so, the succĂšs de scandale of the opera was achieved, in more than one sense, as soon as the curtain rose at Dresdenâs Semperoper on 10 December 1905.
Critics of the premiere noted that the opera set âboundless wildness and degeneration to musicâ; it brought âhigh decadenceâ onto the operatic stage; a âcomposition of hysteriaâ, reflecting the âdisease of our timeâ, Salome is âhardly music any moreâ.The outrage did not end there
Vocal Culture in the Age of Laryngoscopy
For several months beginning in 1884, readers of Life, Science, Health, the Atlantic Monthly and similar magazines would have encountered half-page advertisements for a newly patented medical device called the âammoniaphoneâ (Figure 2.1). Invented and promoted by a Scottish doctor named Carter Moffat and endorsed by the soprano Adelina Patti, British Prime Minister William Gladstone and the Princess of Wales, the ammoniaphone promised a miraculous transformation in the voices of its users. It was recommended for âvocalists, clergymen, public speakers, parliamentary men, readers, reciters, lecturers, leaders of psalmody, schoolmasters, amateurs, church choirs, barristers, and all persons who have to use their voices professionally, or who desire to greatly improve their speaking or singing tonesâ. Some estimates indicated that Moffat sold upwards of 30,000 units, yet the ammoniaphone was a flash in the pan as far as such things go, fading from public view after 1886
Science, Technology and Love in Late Eighteenth-Century Opera
It is a tale told by countless operas: young love, thwarted by an old manâs financially motivated marriage plans, triumphs in the end thanks to a deception that tricks the old man into blessing the young loversâ union. Always a doddering fool, the old man is often also an enthusiast for knowledge. Such is the case, for instance, in Carlo Goldoniâs comic opera libretto Il mondo della luna (1750), in which Buonafedeâs interest in the moon opens him to an elaborate hoax that has him believe he and his daughters have left Earth for the lunar world; and also in the Singspiel Die LuftbĂ€lle, oder der Liebhaber Ă la Montgolfier (1788), wherein the apothecary Wurm trades Sophie, the ward he intended to marry himself, for a technological innovation that will make him a pioneering aeronaut
Operatic Fantasies in Early Nineteenth-Century Psychiatry
In his celebrated essay on insanity in the Dictionnaire des sciences mĂ©dicales (1816), French psychiatrist Ătienne Esquirol marvelled at the earlier custom of allowing asylum inmates to attend theatrical productions at Charenton
