摘要:The transition metal-catalyzed amination of aryl halides, in conjunction with an orthogonal protective group scheme, forms the basis of two routes to oligoaniline precursors. The oligoaniline precursors are soluble in a variety of common organic solvents, and are easily converted to the deprotected oligoanilines. The method allows the preparation of oligoanilines of even or odd chain lengths, and the incorporation of a variety of functional groups into the oligomers. Polyanilines of low polydispersity can also be prepared by this method.

标题:Azidohalogenobenzyl derivatives, sugar compounds and protection of hydroxy groups
发明人：KUSUMOTO SHOICHI; FUKASE KOICHI
权利人:WAKO PURE CHEM IND LTD
摘要:Azidohalogenobenzyl derivatives of the formula (I) ##STR1## wherein A is a halogen atom, B is a halogen atom or a hydrogen atom, and X is a group reactive with a hydroxy group, methods of protecting hydroxy group(s) using said derivatives, and sugar compounds wherein a hydrogen atom of at least one hydroxy group is substituted by an azidohalogenobenzyl group. According to the present invention, there are provided novel derivatives capable of introducing a group into a compound having hydroxy group(s), which group is useful as a stable hydroxy-protecting group even in solid phase synthesis for the purpose of the extension of sugar chain under continuous acidic conditions and of being removed under mild conditions; sugar compounds protected by using said derivatives; and methods of protecting hydroxy group(s) using said derivatives.
