Boyle, Robert. (1627-1691). A native of Ireland, Boyle devoted his life to experiments in what was then called natural philosophy, i.e., physical science. He was influenced early by Galileo. His interest aroused by a pump that had just been invented, Boyle studied the properties of air, on which he wrote a treatise (1660). Soon thereafter, he stated the famous law that bears his name (see following entry). Boyle s group of scientific enthusiasts was known as the invisible college , and in 1663 it became the Royal Society of London. Boyle was one of the first to apply the principle that Francis Bacon had described as the new method —namely, inductive experimentation as opposed to the deductive method of Aristotle—and this became and has remained the cornerstone of scientific research. Boyle also investigated hydrostatics, desalination of seawater, crystals, electricity, etc. He approached but never quite stated the atomic theory of matter however, he did distinguish between compounds and mixtures and conceived the idea of particles becoming associated to form molecules. [Pg.177]

In a similar manner, these researchers have also synthesized [48] a C-8 side-chain analog 60 of domoic acid using a cobalt-mediated cyclization-elimination sequence on the iodide 59 (Scheme 22). They extended this methodology to an enantiospecific total synthesis of acromelic acid A 64, a potent neurotoxin obtained from poisonous mushrooms [46]. The cornerstone of their synthetic strategy was a cobalt-mediated radical cyclization of the substrate 61 which was prepared from the epoxy alcohol in optically pure form. Treatment of 61 with cobalt(I) afforded 62, which was converted to the natural product 64 via pyridone 63 using routine functional group manipulation (Scheme 23). [Pg.147]

Proteins are made up of amino acids, which, as the name implies, include both an amino group and a carboxylic acid. There are 20 essential amino acids and the many hundreds of thousands of proteins are made up of these building blocks. What distinguishes one protein from another is the sequence in which these amino acids are arranged in the molecule. Sequencing has become a cornerstone of the research into proteomics, the study of protein structure and function. There are... [Pg.805]
