Comprehensive Virology: Newly Characterized Vertebrate by David H. L. Bishop, Robert E. Shope (auth.), Heinz PDF

The time turns out ripe for a serious compendium of that section of the organic universe we name viruses. Virology, as a technological know-how, having handed just recently via its descriptive part of naming and num­ bering, has most likely reached that level at which particularly few new-truly new-viruses may be found.

Tobisu and N. Chatani 1 Introduction Chemical synthesis has been revolutionized by the invention of transition metalcatalyzed aromatic substitution reactions of aryl halides (Eq. (1), X ¼ I, Br, Cl) [1]. Among the most powerful are the catalytic cross-couplings wherein organometallic reagents are used as a nucleophilic partner and have emerged as a reliable tool to introduce carbon-based fragments onto an aromatic ring [2, 3]. ” The utility of the crosscoupling reactions has further been expanded by applying heteroatom-centered nucleophiles, such as amines and alcohols [4, 5].

A range of alkoxy groups, including trimethylsiloxy, can be substituted by an aryl group derived from Grignard reagents. Various anisole derivatives, as well as alkoxy-substituted heterocycles, efficiently afford the (hetero)biaryls. Later, Shi applied this catalyst system to the methylation of aromatic [28] and benzylic [29] ethers using MeMgX. Quite recently, Jarvo extended the methylation reaction to secondary benzylic ethers, wherein complete inversion of stereochemistry was observed [30]. ð4Þ The report by Dankwardt clearly indicated that a low-valent nickel complex ligated by a bulky electron-rich phosphine can activate the inert C(aryl)–O bonds in aryl ethers probably through oxidative addition.
