Phosphine diphenyl-, sodium salt

D. ftwis-CHLOROCARBONYLBIS[(ME714-SULFONATOPHENYL) DIPHENYL-PHOSPHINE]IRIDIUM(I), SODIUM SALT (WATER-SOLUBLE ANALOG OF YASKA S COMPLEX)... [Pg.6]

There are a number of important methods worthy of merit for the synthesis of phosphorylglycines. Thus, electrophilic amination of diethyl l-(ethoxycarbonyl)methylphosphonate proceeds in one simple operation via the sodium salt in THF or DME. A variety of aminating agents are used with variable yields, such as 0-mesitylenesulfonylhydroxylamine (39 7%), chloramine (23-84%), and diphenyl (O-hydroxylamine)phosphine oxide (60%). Diethyl 1-ethoxycarbonyl- or l-(tert-butoxycarbonyl)methylphosphonate may also be efficiently transformed into oxime or diazo derivatives and then converted to an amine by a further reduction step. The oximes are prepared from EtONO via the sodium diethyl l-(tert-butoxycarbonyl)methylphosphonate (17% or 36%), from NOCl and diethyl l-(ethoxycarbonyl)methylphosphonate in the presence of tEtOljMg, Al-Hg, or Al(O7-Pr)3, 8 from NOCl and diethyl l-(methoxycarbonyl)ethylphosphonate, ° or from NOCl/ROH and diethyl l-tchlorocarbonyl)mclhy I phosphonate. ... [Pg.433]
