Quinine is a medication used to treat malaria and babesiosis. [5] ... mauveine, was discovered by William Henry Perkin in 1856 while he was attempting to synthesize ...
The subject has also been attended with some controversy: Gilbert Stork published the first stereoselective total synthesis of quinine in 2001, meanwhile shedding doubt on the earlier claim by Robert Burns Woodward and William Doering in 1944, claiming that the final steps required to convert their last synthetic intermediate, quinotoxine, into ...
Some 30 years later in April 1856, William Henry Perkin, then a mere youngster working as assistant at the Royal College of Chemistry in London within a team intent on research over the synthesis of quinine, a potent drug, discovered a process that obtained a purple dye (which he called mauveine) from aniline, which in turn could be easily ...
Letter from Perkin's son, with a sample of dyed silk. Mauveine, also known as aniline purple and Perkin's mauve, was one of the first synthetic dyes. [1] [2] It was discovered serendipitously by William Henry Perkin in 1856 while he was attempting to synthesise the phytochemical quinine for the treatment of malaria. [3]
In 1858 Dr. M. Sales Giron invented the first pressurized inhaler. Amphetamine was first synthesized in 1887 in Germany by Romanian chemist Lazăr Edeleanu who named it phenylisopropylamine ; [ 23 ] [ 24 ] [ 25 ] its stimulant effects remained unknown until 1927, when it was independently resynthesized by Gordon Alles and reported to have ...
Quinine sulfate later proved to be an important remedy for the disease malaria. Quinine is the active anti-malarial ingredient in the bark of cinchona tree. [1] [2] Neither of the partners chose to patent their discovery of this compound, releasing it for everybody to use. In 1823 they discovered nitrogen in alkaloid compounds.
Robert Burns Woodward and William von Eggers Doering successfully synthesized of quinine. This achievement, characterized of fully artificial chemicals as source for synthesis process, opened an era called as "Woodwardian era" or "chemical era" when many drugs and chemicals, as well as organic synthesis methods invented.
In 1867 he discovered that quinine was highly toxic to micro-organisms in impure water, [2] and demonstrated that quinine hydrochlorate with neutral or slightly basic reaction was an effective poison for the protoplasms of decomposing plants and impeded many fermenting and putrid processes. [3]
