Synform Dear Readers, This very rich new issue of SYNFORM is opened by an important new methodology developed by M. Uchiyama (Japan) for preparing, in a very efficient and user-friendly way, stannyl lithium reagents, a class of organometallic compounds which have traditionally posed significant challenges to organic chemists, in spite of their usefulness in synthesis. Notably the method can also be used to prepare the corresponding germanium derivatives. The second article covers a new and very

... clever strategy for achieving the synthesis of β-hydroxy-α-substituted ketones via stereocontrolled addition of Grignard reagents to αepoxy N-sulfonyl hydrazones, a method devised by D. M. Coltart (USA). The next contribution explores the efficient method recently published by S. Fletcher (UK) for performing a highly stereoselective arylation of racemic allylic compounds using a chiral rhodium complex and aryl-boronic acids. The issue is closed by an article exploring the work of K. Hull (USA) on the atom-economical and selective rhodium-catalyzed anti-Markovnikov hydro-amination of homoallylic amines that leads to 1,4-diamines. Enjoy your reading!
